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.
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 randomized 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allocation and measures taken for maintaining its concealment including blinding, numbers treated, followed-up, being withdrawn, dropping out, and having side effects (numbers and type).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. It is now mandatory at JHEP Reports to include all of these details in a completed CTAT methods template table in the Supplementary data.


Results
Results should be clear and concise. Results should be explained and illustrated by using Tables and Figures. 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. List here those individuals who provided help during the research (e.g. providing language help, writing assistance or proof reading the article, etc.)


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 should 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 include a table number, title (in bold), table legend, and if necessary footnotes (including any abbreviations).


Formatting of figures
Figures should be supplied in the following preferred file formats: PDF (*.pdf), PowerPoint (*.ppt), Adobe Illustrator (*.ai, *.eps), files in grayscales or in RGB colour mode.


Photographs (scans, immunofluorescences, EM, and histology images) should be submitted 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 in the supplementary materials. Photographs of identifiable patients should be accompanied by written permission to publish from patient(s).
If after acceptance the quality of the figures does not match the standards of JHEP Reports, the authors will be asked to resubmit the figures at the required quality.


Image integrity and standards
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, JHEP Reports 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


Electrophoretic gels and blots
Positive and negative controls, as well as molecular size markers, should be included on each gel and blot, either in the main figure or an expanded data supplementary figure. For previously characterized antibodies, a citation must be provided. For antibodies less well characterized in the system under study, a detailed characterization that demonstrates not only the specificity of the antibody, but also the range of reactivity of the reagent in the assay, should be published as Supplementary Information or in an antibody profile database (e.g. Antibodypedia, 1DegreeBio).


The display of cropped gels and blots in the main paper is encouraged if it improves the clarity and conciseness of the presentation. In such cases, the cropping must be mentioned in the figure legend.

  • Quantitative comparisons between samples on different gels/blots are discouraged; if this is unavoidable, the figure legend must state that the samples derive from the same experiment and that gels/blots were processed in parallel. Vertically sliced images that juxtapose lanes that were non-adjacent in the gel must have a clear separation or a black line delineating the boundary between the gels. Loading controls (e.g. actin, tubulin, …) must be run on the same blot, if not possible with the same protein aliquot and/or with a red Ponceau coloration of the membrane. Sample processing controls run on different gels must be identified as such, and distinctly from loading controls.
  • Cropped gels in the paper must retain important bands.
  • Cropped blots in the body of the paper should retain at least six band widths above and below the band.
  • High-contrast gels and blots are discouraged, as overexposure may mask additional bands. Authors should strive for exposures with grey backgrounds. Multiple exposures should be presented in supplementary information if high contrast is unavoidable.
  • For quantitative comparisons, appropriate reagents, controls and imaging methods with linear signal ranges should be used.


Microscopic imaging data
JHEP Reports has adopted the policy of the Journal of Cell Biology in requiring the following information regarding microscope image acquisition:

  • Make and model of microscope
  • Type, magnification, and numerical aperture of the objective lenses
  • Temperature
  • Imaging medium
  • Fluorochromes
  • Camera make and model
  • Acquisition software
  • Any software used for image processing subsequent to data acquisition. Please include details and types of operations involved (e.g. type of deconvolution, 3D reconstitutions, surface or volume rendering, gamma adjustments, etc.)


If you export files from a microscope or other acquisition device, be sure to use consistent file formats (8-bit, 16 bit, etc.).


For presentation of fluorescence images, signals from individual channels should be shown in grey scale to reveal the full dynamic range of signal intensities, enabling colour-blind individuals to appreciate your data. Merged images should be presented in colour, with appropriate colours for each individual channel.


Micrographs must include a bar to indicate the scale.


Illustration services
JHEP Reports has an in-house graphic designer who will specifically work on all accepted manuscripts 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.


Figure legends
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 (whether significant or not) should always be included in the figure legends.


An example of how a figure caption should look:


Fig. 1. Levels of AMH in the serum of women who were HCV+, HBV+, or controls. (A) Mean serum levels (bars represent SD and bold lines inside the box plot median levels). Levels of significance: *p = 0.011; ?p = 0.009 (Mann-Whitney U-test). (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.


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.


For revised manuscripts, for all listed citations with two or more authors who share first authorship, JHEP Reports 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.


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. 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 JHEP Reports reference style (see References).
Figures must be included with legends below each figure. Figure legends consist of a title (bold, and labelled Fig. S1) and separate descriptions for each panel, labelled by capital letters in parenthesis. Tables must be included with table titles (bold, and labelled Table S1) 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. 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; Fig. S# and Table S#.


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 databases 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 n.s.). 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 when 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. For more information see http://www.apsstylemanual.org/resources/unitsOfMeasurement/siDerived.htm


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
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.


To help curb the inadvertent use of cross-contaminated or misidentified cell lines, authors are asked to check their reagents against the list of commonly misidentified cell lines maintained by the International Cell Line Authentication Committee (ICLAC; http://iclac.org/databases/cross-contaminations/), also accessible through the NCBI BioSample database. If using a cell line that is on this list, authors should provide a scientific justification and state the identity issue in the methods section.


In the `Materials and methods? section, the source of cells utilized (catalogue number if obtained from vendor or cell bank, 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) and when authentication testing was last performed for that cell line. Authors should be able to provide the test results upon request. Mycoplasma contamination testing status must also be reported.


Please note that it has come to our attention that several cell lines have been contaminated with different cell lines. Therefore, the Journal will no longer consider experiments using BEL7402, SMMC7721, MHCC97L, BEL7404, QGY7701, QGY7703, QSG7701 and SKHEP1 as HCC cell lines, except if the authors provide formal proof of their origin with STR, hepatic gene expression and specific gene mutations. Authors should clearly state this at first submission. For more information please read this Editorial in the Journal of Hepatology: http://dx.doi.org/10.1016/j.jhep.2017.08.002.


Resource Identification Initiative
JHEP Reports encourages authors to use Research Resource Identifiers (RRIDs) for critical reagents and tools.


The Resource Identification Portal allows you to search for antibodies and organism items (e.g. antibodies, model organisms, cell lines, and software) and obtain the appropriate identifiers. Once you have located the RRID, please insert "RRID:" plus the identifier in the appropriate location in the manuscript. For example:

  • Antibodies: "Sections were stained with a rabbit polyclonal antibody against ERK1 (Abgent Cat# AP7251E, RRID: AB_2140114)."


For more information visit the Resource Identification Initiative website.


Genomic and proteomic data
Appropriate data sets (including but not limited to 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/micbbi]).


DNA and protein sequences
Approved databases are GenBank or other members of the International Nucleotide Sequence Database Collaboration (EMBL or DDBJ) and SWISS-PROT.


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 (https://www.ebi.ac.uk/arrayexpress/).
Other large datasets produced using genomics technologies (including but not limited to ChIP on Chip, Genotyping, aCGH, sequencing 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.
