EDITORIAL POLICIES


Ethics in publishing
For information on Ethics in publishing and ethical guidelines for journal publication see http://www.elsevier.com/publishingethics and http://www.elsevier.com/journal-authors/ethics.


Authorship and contributors
As stated in the ICMJE recommendations, credit for authorship requires:
(a) substantial contributions to the conception and design; or the acquisition, analysis, or interpretation of the data,
(b) the drafting of the article or critical revision for important intellectual content,
(c) final approval of the version to be published, and
(d) agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the article are appropriately investigated and resolved. An author contribution statement is required as part of the title page (study concept and design; acquisition of data; analysis and interpretation of data; drafting of the manuscript; critical revision of the manuscript for important intellectual content; statistical analysis; obtained funding; administrative, technical, or material support; study supervision).


Changes to authorship
This policy concerns the addition, deletion, or rearrangement of author names in the authorship of accepted manuscripts. Before the accepted manuscript is published in an online issue, requests to add or remove an author, or to rearrange the author names, must be sent to the Journal Manager at jhepat@elsevier.com from the corresponding author of the accepted manuscript and must include:
(a) the reason the name should be added or removed, or the order of the authors rearranged; and
(b) written confirmation (e-mail, fax, letter) from all authors that they agree with the addition, removal or rearrangement.
In the case of addition or removal of authors, this includes confirmation from the author being added or removed. Requests that are not sent by the corresponding author will be forwarded by the Journal Manager to the corresponding author, who must follow the procedure as described above. Note that: (1) Journal Managers will inform the Journal Editors of any such requests and (2) publication of the accepted manuscript in an online issue is suspended until authorship has been agreed. After the accepted manuscript is published in an online issue, any requests to add, delete, or rearrange author names in an article published will follow the same policies as noted above and result in a corrigendum.


Copyright
Upon acceptance of an article, authors will be asked to complete a 'Journal Publishing Agreement' which contains forms for copyright assignment, financial disclosures and authorship responsibility. An e-mail will be sent to the corresponding author confirming receipt of the manuscript together with a 'Journal Publishing Agreement' form or a link to the online version of this agreement. It is the authors' responsibility to make sure these forms are signed and duly returned to the Editorial office via e-mail or fax. If these forms are not received the manuscript will not be published.


Disclosures

Declaration of interest
All authors are required to provide a Declaration of Interest Statement and should complete a standard form, which is available at www.icmje.org/conflicts-of-interest/. This form should be uploaded with the revised manuscript at submission. Further information is available at http://www.icmje.org/recommendations as well. The forms should be uploaded as a single file as a supplementary material.
All authors are requested to disclose any actual or potential conflict of interest including any financial, personal or other relationships with other people or organisations within three years of beginning the submitted work that could inappropriately influence, or be perceived to influence, their work. If there are no conflicts of interest then please state this: 'Conflicts of interest: none'. See also http://www.elsevier.com/conflictsofinterest. Further information and an example of a conflict of interest form can be found at: http://service.elsevier.com/app/answers/detail/a_id/286/kw/conflict%20of%20interest/p/10523/supporthub/publishing.

Drug declaration
A drug declaration statement/disclosure form will be sent to the corresponding author after acceptance. Authors must select the statement that is most appropriate for their manuscript. This form as well as the copyright forms must be returned to the Editorial office via e-mail or fax.

Submission declaration
Submission of an article implies that the work described has not been published previously (except in the form of an abstract or as part of a published lecture or academic thesis or as an electronic preprint), that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere including electronically in the same form, in English or in any other language, without the written consent of the copyright-holder.

Financial disclosure
Authors are requested to identify who provided financial support for the conduct of the research and/or preparation of the article and to briefly describe the role of the sponsor(s), if any, in study design; in the collection, analysis and interpretation of data; in the writing of the report; and in the decision to submit the article for publication. If the funding source(s) had no such involvement then this should be stated.


Ethics approval
Manuscripts reporting data from research conducted on humans must include a statement of assurance in the methods section of the manuscript reading that: (1) written informed consent was obtained from each patient included in the study and (2) the study protocol conforms to the ethical guidelines of the 1975 Declaration of Helsinki as reflected in a priori approval by the institution's human research committee.


Clinical trials
The International Committee of Medical Journal Editors (ICMJE, http://www.icmje.org) defines a clinical trial as any research project that prospectively assigns human participants to intervention or comparison groups to study the cause-and-effect relationship between an intervention and a health outcome. Interventions include but are not limited to drugs, surgical procedures, devices, behavioral treatments, process-of-care changes, and the like. All manuscripts reporting clinical trials, must include a copy of the trial protocol including the complete statistical analysis plan (if the manuscript is accepted, the protocol will be published as an online supplement), a flow diagram (CONSORT flow diagram), and a completed trial checklist (the CONSORT checklist and template flow diagram can be found at http://www.consort-statement.org). The trial registration number must be included on the title page of the manuscript reporting a registered clinical trial Failure to do so will prevent entry to the peer review process.

Registration of clinical trials
Registration in a public trials registry is a condition for publication of clinical trials in the Journal of Hepatology in accordance with International Committee of Medical Journal Editors (ICMJE, http://www.icmje.org) recommendations. Trials must register at or before the onset of patient enrolment. Purely observational studies (those in which the assignment of the medical intervention is not at the discretion of the investigator) will not require registration.

Acceptable trial registries include the following and others listed at http://www.icmje.org:
http://www.anzctr.org.au
http://www.clinicaltrials.gov
http://isrctn.org
http://www.trialregister.nl/trialreg/index.asp
http://www.umin.ac.jp/ctr

Clinical trial results
In line with the position of the ICMJE, the Journal of Hepatology will not consider results posted in the same clinical trials registry in which primary registration resides to be prior publication if the results posted are presented in the form of a brief structured (less than 500 words) abstract or table. However, divulging results in other circumstances (e.g., investors' meetings) is discouraged and may jeopardise consideration of the manuscript. Authors should fully disclose all posting in registries of results of the same or closely related work.

Randomized control trials
Reports of randomised trials must conform to CONSORT 2010 guidelines. All manuscripts reporting randomized clinical trials, must include a copy of the trial protocol including the complete statistical analysis plan (if the manuscript is accepted, the protocol will be published as an online supplement), a flow diagram (CONSORT flow diagram), and a completed trial checklist (the CONSORT checklist and template flow diagram can be found at http://www.consort-statement.org).
In appropriate places in the manuscript, please provide the following items:

  • The identity of those who designed the protocol and analysed the data.
  • A statement indicating that at least one author had access to all of the data and can vouch for the integrity of the data analyses.
  • Please disclose any funding sources and their role, if any, in the writing of the manuscript or the decision to submit it for publication.
  • Statements of role, if any, of medical writer or editor.


Experimental animal studies
Manuscripts reporting experiments using animals must include a statement giving assurance that all animals received human care and that study protocols comply with the institution's guidelines. Studies involving animal experiments should conform to the Animal Research: Reporting of In Vivo Experiments (ARRIVE) guidelines (http://www.nc3rs.org.uk/arrive-guidelines), developed by the National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs) to improve standards and reporting of animal research. Please review the ARRIVE checklist and disclose all relevant animal research information as directed.
Where applicable the strain and sex should be reported, if both male and females animals were used then the number of each should be specified. In relation to cell cultures and tissue samples used the sex of the animals used should be specified.
Mouse strains and cell lines should be italicized and superscript if they are knockout or transgenic strains, e.g., ob/ob (KO), p53+/+, p53-/-.
Statistical methods used should be outlined, in addition to if sex was considered a factor in the statistical analysis.


Guidelines
Responsible reporting of research studies, which includes a complete, transparent, accurate and timely account of what was done and what was found during a research study, is an integral part of good research and publication practice and not an optional extra. The Journal of Hepatology supports initiatives aimed at improving the reporting of health research. We ask authors to use the following guidelines when drafting their manuscripts:


We ask authors to address all items recommended by the guidelines (as a minimum); where this is not possible please provide an explanation in the text to give a transparent account of your study.
Adherence to recommended reporting guidelines will facilitate review of your manuscript, increase the probability of its successful publication, and improve the usability of research findings from your study in further research and clinical practice.

For more information about these and other guidelines please refer to http://www.equator-network.org.

PREPARING YOUR MANUSCRIPT


YOU DO NOT NEED TO SPECIFICALLY FORMAT YOUR MANUSCRIPT FOR A FIRST SUBMISSION FOR JOURNAL OF HEPATOLOGY.

The following guidelines refer to Research Articles. While published manuscripts are expected to conform tightly to the following guidelines, this is not a requirement at first submission (see the Your Paper, Your Way requirements section below). However, the authors need to ensure that the paper contains all the information that will allow the Editorial team to be able to perform adequate 'peer-review'.


Your Paper, Your Way requirements

  • Authors may submit the first version of their manuscript (text, figures and tables) as a single file. This can be a Word or PDF file, in any format or layout, and figures and tables can be placed within the text.
  • A title page that includes the Title, authors’ names and affiliations, conflict of interest statements, financial support statement and authors’ contributions.
  • Figures should be of high enough quality for refereeing.
  • There are no strict formatting requirements but all manuscripts must contain the essential elements needed to evaluate a manuscript (Abstract, Keywords, Introduction, Materials and Methods, Results, Conclusions, Artwork and Tables with Captions).
  • References can be in any style or format, as long as the style is consistent. Author(s) name(s), journal title/book title, article title (where required), year of publication, volume and issue /book chapter and the pagination must be present. Use of DOIs is highly encouraged. The reference style used by the journal will be applied to the accepted article by Elsevier at the proof stage.

When a paper reaches the revision stage, authors will be requested to deliver any items that are still required for publication, for example editable source files. See details below.


Submission checklist
The Journal of Hepatology now requires a complete author checklist to be submitted with all revised manuscripts.

This should summarize the contents of the article in a concise, pictorial form designed to capture the attention of a wide readership online. Authors must provide images that clearly represent the work described in the article. Graphical abstracts should be submitted as a separate file in the online submission system. We welcome original non-plagiarised artistic styles. Graphical abstracts should be submitted in an editable PDF (*.pdf), Adobe Illustrator (*.ai) or Adobe Photoshop (*.psd) format, fitting within 175 mm in width and max. 200 mm in length (large images). Or 85 mm in width and max. 200 mm in length (smaller images).
The submission of the graphical abstract is mandatory when submitting a revised manuscript, however, the authors are encouraged to include it at submission. For more information and examples please visit http://www.elsevier.com/journal-authors/graphical-abstract

Introduction
State the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results.

Materials/Patients and methods
Provide sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference: only relevant modifications can be described here. All original manuscripts must provide a small materials and methods section, more detailed methods can be referred to and described in the Supplementary data file.
The manuscripts should include a complete and detailed description of what was done. This includes a description of the design, measurement and collection of data, the study objective and major hypotheses, type and source of subjects, inclusion and exclusion criteria and measures of outcome, number of subjects studied and why this number was chosen. Any deviation from the study protocol should be stated. The baseline characteristics of any compared groups should be described in detail and, if necessary, adjusted for in the analysis of the outcome. For randomised clinical trials the following should also be clearly documented: treatments, sample size estimation, method of random allocation and measures taken for maintaining its concealment including blinding, numbers treated, followed-up, being withdrawn, dropping out, and having side effects (numbers and type). Please refer to our Statistics section for further details. Please refer to our Editorial policies section and below for providing details in relation to animal and human trials, drugs and chemicals, genomic and proteomic data, DNA and protein sequencing, microarray data, listing of antibodies and primers.

Results
Results should be clear and concise. Results should be explained and illustrated by using Tables and Figures. There is a maximum of 8 tables and/or figures per original article. Please refer to tables and figures
formatting section.

Conclusions
The conclusions should provide a summary of the key results and discuss the appropriateness and impact of this original piece of work, where necessary referring to the literature to support the new findings.

Acknowledgements
Collate acknowledgements in a separate section at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.)


Formatting of text
The submitted manuscript must be typed double-spaced throughout and pages numbered (including references, tables and figure legends). Preferably using a "standard" font (we prefer Times/Arial 12). For mathematical symbols, Greek letters, and other special characters, use normal text.


Language
Please write your text in good English (American or British usage is accepted, but not a mixture of these). Authors who feel their English language manuscript may require editing to eliminate possible grammatical or spelling errors and to conform to correct scientific English may wish to use the English Language Editing service available from Elsevier's WebShop.


Formatting of tables
Tables should be provided as Word files (*.doc) compatible files. No TIFF, JPG, PDF or PowerPoint files are acceptable. When submitting tables in Microsoft Word use the table function, no tab, space or colours should be used. Tables should contain a maximum of 10 columns. Tables submitted in landscape orientation will not be accepted. Tables should include a table number, title (in bold), table legend, and if necessary footnotes (including any abbreviations). Include tables in the submitted manuscript as a separate section at the end of the manuscript.


Formatting of figures
All graphics submitted to the Journal of Hepatology should be sent at their actual size, which is 100% of their print dimension and in portrait orientation.
Two standard widths are used and figures should fit in one (8.5 × 22.0 cm) or two (17.5 × 22.0 cm) columns.
Figures should be supplied in the following preferred file formats: PDF (*.pdf), PowerPoint (*.ppt), Adobe Illustrator (*.ai, *.eps), Photoshop (*.psd) files in grayscales or in RGB colour mode. It is highly recommended that figures not be sent in JPG (*.jpg) format.
Photographs (scans, immunofluorescences, EM, and histology images) should be submitted as: 1) TIFF (*.tif) with a resolution of at least 300 pixels per inch; or 2) Illustrator compatible EPS files with RGB colour management (*.eps); or 3) Photoshop (*.psd) or editable PDF (*.pdf) files (grayscales or RGB) at the appropriate resolution which is:

  • 300 dpi for colour figures
  • 600 dpi for black and white figures
  • 1200 dpi for line-art figures

For all photomicrographs, when possible, a scale bar should appear on the photograph. For Western blots original blots must be provided. Photographs of identifiable patients should be accompanied by written permission to publish from patient(s).
Panel lettering should be in Arial bold 14 pt, capitalized and no full stop (A, B) while lettering in figures (axes, conditions), should be in Arial 8 pt, lower case type with the first letter capitalized and no full stop. No type should be smaller than 6 pt.
If after acceptance the quality of the figures does not match the standards of the Journal of Hepatology, the authors will be asked to resubmit the figures at the required quality.


Image manipulation
While it is accepted that authors sometimes need to manipulate images for clarity, manipulation for purposes of deception or fraud will be seen as scientific ethical abuse and will be dealt with accordingly. For graphical images, the Journal of Hepatology is applying the following policy:
No specific feature within an image may be enhanced, obscured, moved, removed, or introduced.
Adjustments of brightness, contrast, or colour balance are acceptable if and as long as they are done in the whole figure (not in specific parts of it) and do not obscure or eliminate any information present in the original. Nonlinear adjustments (e.g., changes to gamma settings) must be disclosed in the figure legend.
Grouping of images from parts of a gel/different gels must be made explicit.
Please follow the CSE's guidelines for more information: http://www.councilscienceeditors.org/resource-library/editorial-policies/white-paper-on-publication-ethics/3-4-digital-images-and-misconduct

Illustration services
The Journal of Hepatology has an in-house graphic designer who will specifically work on all accepted manuscript to format the tables/figures to comply with the Journal's style. Upon acceptance the corresponding author will be asked to complete a form stating that the author gives permission to re-design graphics. This form, along with the copyright and drug declaration forms, must be returned to the Editorial office via e-mail or fax.


Figure legends
Figure legends should be listed one after the other, as part of the text document, separate from the figure files. Please do not write a legend below each figure.
Each figure legend should have a brief overarching title (in bold with figure number) that describes the entire figure without citing specific panels, followed by a description of each panel, and the symbols used. Enough information should be provided in the figure legend text to permit interpretation of figures without reference to the text, but should not contain any details of methods, or exceed 100 words.
The statistical test used as well as the values of statistical significance should be always included in the figure legends.
The abbreviated word for figure "Fig." should be typed and bolded, followed by the figure number and a period (i.e., "Fig. 1."). Every figure legend should have a title written in bold. If a figure contains multiple sections (i.e., A, B, C, D) the letter for these subsections should be in capital letters, and should be surrounded by parenthesis [i.e., (A)…(B)…(C)…(D)]. Figures should be numbered according to the order of citation.

An example of how a figure caption should look:

Fig. 4. The general leukocyte recruitment paradigm and its peculiarities in the liver. (A) In most tissues, leukocytes (i.e., neutrophils) initially tether the endothelium adjacent to the inflammatory focus, where they start to roll until firm adhesion. Once adhered to the vessel wall, leukocytes crawl towards "hot spots" within the lumen, and finally, following a chemotactic gradient, they reach the extravascular compartment to accumulate in areas rich in chemokines, bacterial products or necrosis-derived molecules. (B) ….


References
Responsibility for the accuracy of bibliographic citations lies entirely with the authors.There are no strict requirements on reference formatting at submission. References can be in any style or format as long as the style is consistent.


An example of how references should look within the text:

HVPG was measured by hepatic vein catheterization using a balloon catheter according to a procedure described elsewhere [14,15] and used as an index of portal hypertension [16].


An example of how the reference list should look:

[14] Merkel C, Bolognesi M, Bellon S, Zuin R, Noventa F, Finucci G, et al. Prognostic usefulness of hepatic vein catheterization in patients with cirrhosis and esophageal varices. Gastroenterology 1992;102:973-979.
[15] Groszmann RJ, Wongcharatrawee S. The hepatic venous pressure gradient: anything worth doing should be done right. Hepatology 2004;39:280-282.


Citation in text
References are ordered as they appear in the text. Titles of all cited articles are required. All articles in the list of references should be cited in the text and, conversely, all references cited in the text must be included in the list. Personal communications and unpublished data should be cited directly in the text by the first author, without being numbered.


Reference links
Updated versions of the Journal of Hepatology EndNote® and Reference Manager® styles can be found here:

RefMan: ftp://support.isiresearchsoft.com/RefMan/Styles/Journal%20of%20Hepatology.os
EndNote: ftp://support.isiresearchsoft.com/pub/pc/styles/endnote4/J%20Hepatology.ens

For revised manuscripts, the authors need to check all the citations in the Reference Section. For all listed citations with two or more authors who share first authorship, the Journal of Hepatology stipulates those authors' names to be in bold type. It is the corresponding and first authors' responsibility to ensure that these names appear in bold in the reference section when submitting a revised draft (first drafts of submissions are exempt from this requirement). This allows giving due credit to joint-first- authors (see the "Editorial" in the February 2015 issue of Journal of Hepatology for more on this topic). Also, please include the phrase "Author names in bold designate shared co-first authorship" at the beginning of the references section if you have citations that have joint first authors. Example: (Smith T, Jones R, Davis G, et al. Article title).

Web references
As a minimum, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author names, dates, reference to a source publication, etc.), should also be given. Web references can be listed separately (e.g., after the reference list) under a different heading if desired, or can be included in the reference list.


Data references
This journal encourages you to cite underlying or relevant datasets in your manuscript by citing them in your text and including a data reference in your Reference List. Data references should include the following elements: author name(s), dataset title, data repository, version (where available), year, and global persistent identifier. Add [dataset] immediately before the reference so we can properly identify it as a data reference. This identifier will not appear in your published article.


An example of how such a reference should look:

[5] Oguro M, Imahiro S, Saito S, Nakashizuka T. Mortality data for Japanese oak wilt disease and surrounding forest compositions, Mendeley Data, v1; 2015. http://dx.doi.org/10.17632/xwj98nb39r.1.


Supplementary data
Supplementary material, can be uploaded during the submission process.

The Supplementary material should have a manuscript title, list of authors, a table of contents, followed by the list of investigators (if there is one), text (such as methods), figures, tables, and then references. Supplementary material must be prepared as a single Word file with pages numbered (including references, tables and figure legends) using Times New Roman or Arial 12 pt double-spaced. Sections have to be 12 pt bold, subsections have to be 12 pt, italics. For mathematical symbols, Greek letters, and other special characters, use normal text, NOT symbol. The references must be in accordance with the Journal of Hepatology reference style (see References).
Figures have to be included with legends below each figure. Figure legends consist of a title (bold, and labelled Supplementary Fig. 1) and separate descriptions for each panel, labelled by capital letters in parenthesis. Tables have to be included with table titles (bold, and labelled Supplementary Table 1) on top of the table and footnotes below. Very large tables (e.g., microarray data) should be submitted as Excel files.The Supplementary material will NOT be edited for style.

Supplementary movies may be submitted through Elsevier Editorial System as (*.mov), (*.avi), (*.mpeg), or (*.gif) files. By choosing the submission item labelled "Supplementary data," the PDF builder will imbed links within the PDF where Editors and reviewers will be able to download the files. This also works for Excel files that do not display properly once converted to a PDF. Please note that the size limit for these items is 10 MB per file.
Large data sets (too large to be included within the manuscript) must be submitted online. Each file should be prepared as PDF, Excel, or text. The size of the file should not exceed 10MB.Upon acceptance, if Supplementary material does not comply with the guidelines authors will be requested to change the formatting.
All supplementary data referred to in the main manuscript must be labelled as: Supplementary Materials & methods; Supplementary Fig. # and Supplementary Table #.


Cover illustrations
Cover illustrations will be chosen by the Editors. The Editors may decide to exhibit an illustration from an accepted paper on the cover. If this is the case, the Journal of Hepatology office will be in touch to request higher quality images.


Statistics
The statistical methods used should be relevant and clearly stated. Special or complex statistical methods should be explained and referenced. Complex analyses should be performed with the assistance of a qualified statistician and should be extensively described in the supplemental material to ensure reproducibility of the results together with an access to the primary results in public database or upon request. Unqualified use of such analyses is strongly discouraged. The underlying assumptions of the statistical methods used should be tested to ensure that the assumptions are fulfilled. For small data sets and if variable distributions are non-normal, distribution free (non-parametric) statistical methods should be used. The actual p values - whether significant or not - should always be presented (not NS). Confidence intervals convey more information than p values and should be presented whenever possible. Continuous variables can always be summarized using the median and range which are therefore preferred. Only in the infrequent case of a normal distribution are the mean and standard deviation (SD) useful. Complex analyses (including Cox and logistic regression analysis) should be presented in sufficient detail: i.e., variable scoring, regression coefficients, standard errors and any constants. Odds-ratios or relative risks are not sufficient documentation of such analyses. The handling of any missing values in the data should be clearly specified. The number of statistical tests performed should be kept at a minimum to reduce spurious positive results. Explorative (hypothesis generating) analyses without confirmation using independent data are discouraged. Figures showing individual observations e.g., scatter plots are encouraged. Histograms may also be useful. Tables should indicate the number of observations on which each result is being based. A statistical review of the paper will be sought from an expert where necessary.


Units
Follow internationally accepted rules and conventions: use the internal system of units (SI). If other units are mentioned please give their equivalent in SI.


Drugs and chemicals
The source of reagents should be stated (name, city, and state within parentheses) when first cited. Drugs and chemicals should be used by generic name. If trademarks are mentioned, proprietary (trademarked) names should be capitalized, with the spelling carefully checked. The generic name or generic descriptor accompany the trade name the first time it appears.Other data relating to unique biological, biochemical, and/or immunological markers should also be included if available, with their source identified.


Cell lines
In the Materials and methods section, the source of cells utilized (species, sex, strain, race, age of donor, whether primary or established) should be clearly indicated. The Methods section should state if cell line authentication has been carried out and by what method (e.g., STR profiling). If tests to rule out the presence of mycoplasmal contamination were not performed, this fact should be clearly stated. See also standards for cell line authentication.
It is recommended that results should be replicated using more than one cell line. When using primary cells a minimum of three different batches should be used.


Genomic and proteomic data
The Journal of Hepatology supports the efforts of databases that aggregate published data for the use of the scientific community. Therefore, appropriate data sets (including microarray data, protein or DNA sequences) must be deposited in an approved database, and an accession number or a specific access address must be included in the published paper. When working with publicly available databases the provenance of the data and the release number should be clearly indicated.
We encourage compliance with MIBBI guidelines (Minimum Information for Biological and Biomedical Investigations [http://www.biosharing.org/standards/mibbi]).

DNA and protein sequences
Approved databases are GenBank or other members of the International Nucleotide Sequence Database Collaboration (EMBL or DDBJ) and SWISS-PROT.
For gene and protein names, all genes should be in italics and all proteins non-italicized. For murine the gene name should be in lowercase except the first letter e.g., gene: Abcb4; protein: Abcb4. For humans, the whole gene name is capitalized and italicized, the protein is non-italicized e.g., gene: ABCB4; protein ABCB4.

Microarray data
Data should be presented in MIAME-compliant standard format (http://www.fged.org/projects/miame/). Approved databases are Gene Expression Omnibus (http://www.ncbi.nlm.nih.gov/geo/) and ArrayExpress (/www.ebi.ac.uk/arrayexpress/).
Other large datasets produced using genomics technologies (including but not limited to ChIP on Chip, Genotyping, aCGH and Tilling Arrays) must be deposited in an appropriate public repository. Please include the repository URL and the data accession number in the body of the manuscript upon submission. Data must be publicly accessible upon acceptance and publication of the manuscript as a Paper in Press. No data are to be withdrawn following publication.


Database linking
Elsevier encourages authors to connect articles with external databases, giving readers access to relevant databases that help to build a better understanding of the described research. Please refer to relevant database identifiers using the following format in your article: Database: xxxx (e.g., TAIR: AT1G01020; CCDC: 734053; PDB: 1XFN). See http://www.elsevier.com/databaselinking for more information and a full list of supported databases.


List of antibodies
Authors who use antibodies for immunohistochemistry, immunocytochemistry, Western blots should include an antibody table indicating all antibodies used. This table should be included in the Supplementary data. This table should indicate catalog number (and/or clone number) or primary citation for each antibody, appropriate positive and negative controls, validation of each antibody and any necessary references.


Audioslides
The Journal of Hepatology encourages authors to create an AudioSlides presentation with their published article. AudioSlides are brief, webinar-style presentations that are shown next to the online article on ScienceDirect. This gives authors the opportunity to summarize their research in their own words and to help readers understand what the paper is about. More information and examples are available at http://www.elsevier.com/audioslides. Authors of this journal will automatically receive an invitation e-mail to create an AudioSlides presentation after acceptance of their paper.

REVIEW PROCESS
Authors should be aware that manuscripts will be screened upon submission. Only the manuscripts, which fully comply with the submission requirements outlined and in which the level of English is of an acceptable standard will enter the peer review process.


First submission
Once successful submission of a manuscript has taken place, an acknowledgement will be sent by e-mail to the corresponding author on the manuscript. All subsequent correspondence will be with the designated corresponding author. The number of the manuscript should be used by the authors in all communications with the Editorial Office. All the manuscripts will be reviewed by the Editors and papers that are not considered by the editors to be strong candidates for publication or outside the scope of the Journal will be returned to the authors without detailed review, typically within 3-5 days. Otherwise, manuscripts will be sent to reviewers. After review, the corresponding author will be notified by letter of the decision taken by the Editor(s). This letter will be accompanied in most, but not all, cases by the comments of the reviewers. This letter will be sent via e-mail.


Resubmission
Resubmission of manuscripts. In some cases, authors will be invited to submit a revised version of the manuscript for further review. This invitation does not imply, in any case, that the revised version will be accepted for publication. In general, revised manuscripts must be received in the Editorial Office within four months of the date of the first decision. Authors should submit the resubmitted manuscript with all changes underlined. The resubmitted manuscript should be accompanied by a cover letter stating that the manuscript has been revised according to the comments made by the Editor and the Reviewers. Figures and tables must be uploaded. Please ensure that a separate point by point response to the reviewers is included with the covering letter.
Please do not send revised manuscripts to the Editorial Office via e-mail. Revised manuscripts should be uploaded in the Elsevier Editorial System website.


Proofs
Proofs will be made available to the author(s) to be checked. It is the responsibility of the author(s) to make sure that the quality and accuracy of the manuscript, figures, and tables in the proofs is correct. Authors should return their proofs within 48 hours, by fax or e-mail if the corrections are minor, to expedite publication. All questions arising after acceptance of a paper, especially those concerning proofs, should be directed to the Publisher, Elsevier, Radarweg 29, 1043 NX Amsterdam, The Netherlands, tel.: +31 (0)20 485 2533, fax: +31 (0)20 485 2521, e-mail: JHEPAT@elsevier.com. Further changes or additions to the edited manuscript after these corrections cannot be accepted.


Publishing fees
Submission and publication is free of charge. Journal of Hepatology has a graphic design team that is responsible for re-stylizing all tables, charts, and figures to improve the readability and presentation of the Journal of Hepatology, as well as to give it a unique style that is present across all articles. This service is free of charge.
Colour figures using colours different from the Journal of Hepatology colours (e.g., Immunofluorescence, photographs) are charged if the figures appear in colour in the printed version. Colour figures online only are free of charge.


Funding body agreements and policies
