Atherosclerosis is a fully electronic journal, all manuscripts are to be submitted via the internet. To submit your paper online, click on the link http://ees.elsevier.com/ath/.
Original Research Papers are divided into three categories:
- Basic Research Papers reporting results of original research or investigation using in vitro cell culture or animal models.
- Clinical and Population Research Papers reporting results of investigation in human subjects including observational, interventional and genetic studies. Meta-analyses and genetic association studies will also be published under this category. For publication of clinical trials, genetic association studies and meta-analyses, please consult the dedicated Special Guidelines below.
- Translational Research Papers reporting results of research from both bench-to-bedside and bedside-to-bench.
Rapid Communications. Authors may choose to submit their Original Research Paper as Rapid Communication. These papers should provide a brief but complete account of important new observations that merit urgent publication. Authors should clearly state in the covering letter why the paper merits urgent publication. The Editor-in-Chief will normally reach a decision on these papers within three weeks. Papers requiring revision will not be considered as Rapid Communications. The following word limits apply: abstract 150 words, main text 3000 words (including legends to figures and tables), 3 figures and/or tables in total, and a maximum of 25 references.Atherosclerosis welcomes submissions of manuscripts previously rejected by high-quality journals because of priority reasons. Please submit your manuscript together with a cover letter and the reviewers’ comments via the journal submission system (http://ees.elsevier.com/ath/) by choosing Rapid Communication as article type.Your manuscript and the reviewers’ comments will be assessed by the Editor in Chief and Co-Editors, who will decide within one week whether the paper is accepted or not, with or without any revision.
Review Articles. Atherosclerosis publishes review articles on topics of great interest or controversy in basic, translational, clinical or population research. Authors who have not been priorly invited to submit a Review by the Editors of Atherosclerosis are advised to write a letter of interest to the Editorial Office, accompanied by an abstract. Based on this, the Editors will encourage or discourage submission. In all cases, Review Articles undergo peer review. The following word limits apply: abstract 250 words, main text 5000 words, 6 figures and/or tables in total, and a maximum of 100 references. Authors are encouraged to include a "mechanism/overview" figure and one or more bullet point boxes highlighting the main key-points.
Clinical and Scientific Debates on Atherosclerosis. In this review, two antipodal experts are invited to debate their opposing views on a relevant topic, where every argument is discussed by the author in favour and the author against. Debates articles will consist of an abstract (250 words), a pro section (2500 words) and a con section (2500 words). A total of 6 figures/tables is accepted. References should not exceed a maximum of 100.Conference reports. Conference reports are accepted for publication in our Journal and should be structured as follows: 1) authors and contact details (postal address of all authors and email address of corresponding author); 2) name of the conference and name of the organizing national atherosclerosis society); 3) conference dates and venue, and website address if available; 4) name(s) of conference President(s); 5) topics covered by the conference as bullet points; 6) conference highlights (prosa or bullet points); 7) conflict of interest statement with respect to the congress (e.g. sponsorship). 1 one-column width figure is allowed. The word count of the entire report (items 1 through 6) shall not exceed 450 words.

Your Paper Your Way
We now differentiate between the requirements for new and revised submissions. You may choose to submit your manuscript as a single Word or PDF file to be used in the refereeing process. Only when your paper is at the revision stage, will you be requested to put your paper in to a 'correct format' for acceptance and provide the items required for the publication of your article.
To find out more, please visit the Preparation section below.
This journal operates a single blind review process. All contributions will be initially assessed by the editor for suitability for the journal. Papers deemed suitable are then typically sent to a minimum of two independent expert reviewers to assess the scientific quality of the paper. The Editor is responsible for the final decision regarding acceptance or rejection of articles. The Editor's decision is final.
Please ensure the Atherosclerosis style is followed for all revised papers and the checklist uploaded with the revised manuscript Atherosclerosis Checklist
• Title. Concise and informative. Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible.
• Author names and affiliations. Please clearly indicate the given name(s) and family name(s) of each author and check that all names are accurately spelled. You can add your name between parentheses in your own script behind the English transliteration. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name and, if available, the e-mail address of each author.
• Corresponding author. Clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication. This responsibility includes answering any future queries about Methodology and Materials. Ensure that the e-mail address is given and that contact details are kept up to date by the corresponding author.
• Present/permanent address. If an author has moved since the work described in the article was done, or was visiting at the time, a 'Present address' (or 'Permanent address') may be indicated as a footnote to that author's name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.
A structured Abstract must be provided to include the following four sections: Background and aims, Methods, Results; Conclusions (a maximum of 250 words for regular original research papers).
The manuscript main text must be structured to include the following sections in this order (please do not deviate from the headers provided):
- Materials and methods (or Patients and methods)
- Conflict of interest (mandatory)
- Financial support (if applicable)
- Author contributions (mandatory)
- Acknowledgements (if applicable)
Abbreviations should be defined when first used in the text. Use of abbreviations should be kept at a minimum.
Tables must be submitted as Word files. Tables with titles and legends must be on separate pages with double spacing; they may be included in the same file as the manuscript text or in separate file(s). Authors must list on the title page or in the covering e-mail, the number of figures and/or tables to be found in the paper.
Footnotes to tables must be listed with superscript lowercase letters, beginning with "a."
Footnotes must not be listed with numbers or symbols.
Each figure and table legend should have a brief overarching title (with figure number) that describes the entire figure without citing specific panels, followed by a description of each panel, and all symbols used.
If a figure or table contains multiple panels, the letter describing each panel should be capitalized and surrounded by parenthesis: i.e. (A)(B)(C)(D).
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. Where applicable, author(s) name(s), journal title/book title, chapter title/article title, year of publication, volume number/book chapter and the pagination must be present. For authors' name, the general rule is up to 5 names before et al. Use of DOI is highly encouraged. The reference style used by the journal will be applied to the accepted article by Elsevier at the proof stage. Note that missing data will be highlighted at proof stage for the author to correct.
For murine models, the gene and protein names are lowercase except for the first letter(e.g. gene: Abcb4; protein: Abcb4).
For humans, the whole gene name is capitalized(e.g. gene: ABCB4; protein ABCB4).Only gene names approved by the HUGO Gene Nomenclature Committee should be used: www.genenames.org.
Mouse strains and cell lines: Knock-out or transgenic mouse strains and cell lines are italicized and the symbol superscripted (e.g. ob/ob , p53+/+, p53-/-).
All p are italicized and lower case.http://webshop.elsevier.com/languageediting/ or visit our customer support site http://support.elsevier.com for more information

Data in Brief
You have the option of converting any or all parts of your supplementary or additional raw data into one or multiple data articles, a new kind of article that houses and describes your data. Data articles ensure that your data is actively reviewed, curated, formatted, indexed, given a DOI and publicly available to all upon publication. You are encouraged to submit your article for Data in Brief as an additional item directly alongside the revised version of your manuscript. If your research article is accepted, your data article will automatically be transferred over to Data in Brief where it will be editorially reviewed and published in the open access data journal, Data in Brief. Please note an open access fee of 500 USD is payable for publication in Data in Brief. Full details can be found on the Data in Brief website. Please use this template to write your Data in Brief.
You have the option of converting relevant protocols and methods into one or multiple MethodsX articles, a new kind of article that describes the details of customized research methods. Many researchers spend a significant amount of time on developing methods to fit their specific needs or setting, but often without getting credit for this part of their work. MethodsX, an open access journal, now publishes this information in order to make it searchable, peer reviewed, citable and reproducible. Authors are encouraged to submit their MethodsX article as an additional item directly alongside the revised version of their manuscript. If your research article is accepted, your methods article will automatically be transferred over to MethodsX where it will be editorially reviewed. Please note an open access fee is payable for publication in MethodsX. Full details can be found on the MethodsX website. Please use this template to prepare your MethodsX article.
To foster transparency, we encourage you to state the availability of your data in your submission. This may be a requirement of your funding body or institution. If your data is unavailable to access or unsuitable to post, you will have the opportunity to indicate why during the submission process, for example by stating that the research data is confidential. The statement will appear with your published article on ScienceDirect. For more information, visit the Data Statement page.

Authors are expected to consider carefully the list and order of authors before submitting their manuscript and provide the definitive list of authors at the time of the original submission. Any addition, deletion or rearrangement of author names in the authorship list should be made only before the manuscript has been accepted and only if approved by the journal Editor. To request such a change, the Editor must receive the following from the corresponding author: (a) the reason for the change in author list and (b) written confirmation (e-mail, 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.
Only in exceptional circumstances will the Editor consider the addition, deletion or rearrangement of authors after the manuscript has been accepted. While the Editor considers the request, publication of the manuscript will be suspended. If the manuscript has already been published in an online issue, any requests approved by the Editor will result in a corrigendum.
Upon acceptance of an article, authors will be asked to complete a 'Journal Publishing Agreement' (see more information on this). 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.
For gold open access articles: Upon acceptance of an article, authors will be asked to complete an 'Exclusive License Agreement' (more information). Permitted third party reuse of gold open access articles is determined by the author's choice of user license.Author rights
As an author you (or your employer or institution) have certain rights to reuse your work. More information.
Role of the funding source
You 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.
Elsevier has established a number of agreements with funding bodies which allow authors to comply with their funder's open access policies. Some funding bodies will reimburse the author for the gold open access publication fee. Details of existing agreements are available online.
• Articles are made available to subscribers as well as developing countries and patient groups through our universal access programs.
• No open access publication fee payable by authors.
• The Author is entitled to post the accepted manuscript in their institution's repository and make this public after an embargo period (known as green Open Access). The published journal article cannot be shared publicly, for example on ResearchGate or Academia.edu, to ensure the sustainability of peer-reviewed research in journal publications. The embargo period for this journal can be found below.
Gold open access
• Articles are freely available to both subscribers and the wider public with permitted reuse.
• A gold open access publication fee is payable by authors or on their behalf, e.g. by their research funder or institution.
Members of the European Atherosclerosis Society (EAS) benefit from a 25% reduction on the open access publication fee (as senior or corresponding authors of accepted papers)Regardless of how you choose to publish your article, the journal will apply the same peer review criteria and acceptance standards.
For gold open access articles, permitted third party (re)use is defined by the following Creative Commons user licenses:Creative Commons Attribution-NonCommercial-NoDerivs (CC BY-NC-ND)
For non-commercial purposes, lets others distribute and copy the article, and to include in a collective work (such as an anthology), as long as they credit the author(s) and provided they do not alter or modify the article.Green Open Access
Authors can share their research in a variety of different ways and Elsevier has a number of green open access options available. We recommend authors see our green open access page for further information. Authors can also self-archive their manuscripts immediately and enable public access from their institution's repository after an embargo period. This is the version that has been accepted for publication and which typically includes author-incorporated changes suggested during submission, peer review and in editor-author communications. Embargo period: For subscription articles, an appropriate amount of time is needed for journals to deliver value to subscribing customers before an article becomes freely available to the public. This is the embargo period and it begins from the date the article is formally published online in its final and fully citable form. Find out more. Use of the Digital Object Identifier
The Digital Object Identifier (DOI) may be used to cite and link to electronic documents. The DOI consists of a unique alpha-numeric character string which is assigned to a document by the publisher upon the initial electronic publication. The assigned DOI never changes. Therefore, it is an ideal medium for citing a document, particularly 'Articles in press' because they have not yet received their full bibliographic information. Example of a correctly given DOI (in URL format; here an article in the journal Physics Letters B): http://dx.doi.org/10.1016/j.physletb.2010.09.059
When you use a DOI to create links to documents on the web, the DOIs are guaranteed never to change.Elsevier will do everything possible to get your article corrected and published as quickly and accurately as possible. Therefore, it is important to ensure that all of your corrections are sent back to us in one communication. Subsequent corrections will not be possible, so please ensure your first sending is complete
PDF offprints are provided free of charge. No reprints are provided free of charge. Reprints (50 copies minimum) can be ordered at quoted prices on order forms sent out together with the proofs.
Corresponding authors will receive an e-mail with a link to our online proofing system, allowing annotation and correction of proofs online. The environment is similar to MS Word: in addition to editing text, you can also comment on figures/tables and answer questions from the Copy Editor. Web-based proofing provides a faster and less error-prone process by allowing you to directly type your corrections, eliminating the potential introduction of errors.
If preferred, you can still choose to annotate and upload your edits on the PDF version. All instructions for proofing will be given in the e-mail we send to authors, including alternative methods to the online version and PDF.
We will do everything possible to get your article published quickly and accurately. Please use this proof only for checking the typesetting, editing, completeness and correctness of the text, tables and figures. Significant changes to the article as accepted for publication will only be considered at this stage with permission from the Editor. It is important to ensure that all corrections are sent back to us in one communication. Please check carefully before replying, as inclusion of any subsequent corrections cannot be guaranteed. Proofreading is solely your responsibility.

The International Committee of Medical Journal Editors (ICMJE) defines a clinical trial as any research project prospectively assigning 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, 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 and in the Materials and methods section. Failure to do so will prevent entry to the peer review process.
Registration in a public trials registry is a condition for publication of clinical trials in Atherosclerosis in accordance with International Committee of Medical Journal Editors (ICMJE) recommendations. Trials must be registered 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.Clinical trial results
In line with the position of the ICMJE, Atherosclerosis 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, 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).Guidelines for genetic association papers
Atherosclerosis is interested in publishing genetic association papers that present data that is novel, statistically robust, clinically relevant and that add significantly to the field. Authors are advised to follow the reporting guidelines outlined in the STREGA Statement (http://www.strega-statement.org) , and to achieve this, the following criteria should be met.
1. All the following aspects should be addressed appropriately and Methods used should be reported:a) Population stratification should be addressed in case of admixed populations;
b) Test on Hardy-Weinberg-Equilibrium must be carried out and the p value reported;c) LD-structure between SNPs (if multiple SNPs are reported) must be presented;
d) Genotyping errors / call rate must be reported;e) Appropriate correction for multiple testing (if multiple independent SNPs are reported) must be included;
f) Possible relatedness between studied subjects must be documented and addressed if present.2. All papers must include a power calculation to estimate the effect the size the study has the power to detect, based on sample size and minor allele frequency of the included SNPs. If power calculations are not included the paper is likely to be rejected without review. It should be stated whether or not power calculations were performed before or after study completion. Comment: The study should have an adequate sample size. Ideally, power calculations should have been performed before conducting the study since post-hoc power calculations are often a self-fulfilling prophecy. It should be stated whether or not power calculations were performed before or after study completion. Several programs are available to perform power and/or sample size calculations for genetic association studies, e.g. the "Genetic Power Calculator" (http://pngu.mgh.harvard.edu/~purcell/gpc) , and see table 1 below. Sample size and /or Power calculations on two-stage designs can be calculated e.g. by using the program CATS (http://www.sph.umich.edu/csg/abecasis/CaTS)  for case-control studies and QpowR (https://www.msu.edu/~steibelj/JP_files/QpowR.html) for studies on quantitative traits. Since genetic association studies often involve more complex study designs involving meta-analysis or several replication stages, simple answers on required sample sizes cannot be given. Authors are advised, however, to keep this issue in mind and give a good rationale, if the study is clearly underpowered.
3. For any novel association a replication study must be included in the submitted manuscript. Any novel association not including a replication study may be rejected without review. Comment: The presentation of novel association results requires replication in most cases, if appropriate replication studies exist. However, if the first study has already an appropriate sample size (considering that very large studies with several thousands of individuals are available) and if the results show a strong association, it might not be necessary to provide a replication. Furthermore, giving additional evidence from other sources could replace replication studies, if they are convincing, e.g. results from functional experiments. Meta-analysis on the discovery stage or other outstanding studies do also not require replication in every case, but it should be clear that these are exceptional cases and have to discussed in that way to be acceptable for publication.
4. For any association study replicating a previously published finding, there should be sufficient novelty to add significantly to the literature. This could include confirming the effect size in a different ethnic group, or extending the association observations to additional intermediate traits or disease groups. Any study not having sufficient novelty is likely to be rejected without review.
6. Generally, authors should present the rationale as to why gene regions and SNPs have been selected. Association studies using SNPs where previous studies have demonstrated that the base change has an effect on protein function or gene expression will be favored over those using SNPs where no functionality has been previously determined. Studies using a tagSNP approach will also be considered, where these add additional data to the already known variations, in order to further explain observed associations.References

Nat Genet (2006) 38:209-13.In the following table, some sample sizes are given, calculated from the "Genetic Power Calculator", assuming an alpha-level of = 0.05, an additive inheritance model, an assumed prevalence of disease of 30% and a power of 80% for a balanced case-control study (1:1 case:control ratio) for varying minor allele frequencies (MAF) and genetic relative risks (GRR). Relative risks of between 1.1 and 1.3 are in the range that can be expected in genetic association studies on complex diseases. Guidelines for meta-analyses
In principle, literature-based meta-analyses should be reported in that way, that any interested researcher is able to reproduce the results. To ensure this, authors are strongly advised to follow the guidelines listed below and are further encouraged to use the PRISMA (http://www.prisma-statement.org/PRISMAStatement/Default.aspx) and the MOOSE statements (http://jama.ama-assn.org/cgi/content/full/283/15/2008) as a guide. Therefore, as much information as needed should be provided. However, for the average reader only the most mandatory information should be reported in the main paper with additional information given in the Supplementary Material.
1. Specification of objective and primary study outcome. If there are previous meta-analyses on the same outcome available, the authors should specify clearly the differences and added value of their meta-analysis in a separate section ("Added value to previous meta-analysis on the same topic").2. Detailed specification of search strategy, study selection strategy (including approaches to reach unpublished studies) and eligibility criteria for studies. It is highly recommended to use a graphical Flow Chart (templates available at http://www.prisma-statement.org/PRISMAStatement/Default.aspx).
3. Description of possible sources of bias and confounding and strategies to prevent them. This includes:
- Bias in individual studies
- Bias across studies (e.g. publication bias, selective reporting within studies)
- Quality and comparability of studies (study types, study outcomes, sample size)
- What is the primary summary measure (Difference in Mean, OR, etc.)? How was it extracted from the individual studies (e.g. calculated from raw numbers or tables or taken as reported)
- Methods to assess heterogeneity and bias
- Methods used for the combined analysis (fixed effects, random effects) including a rationale for using this method.
5. Reporting of results:
- Individual study characteristics (including sample size, study type, population/ethnicity, primary outcome, reference)
- Individual study results (effect estimates including confidence intervals or standard errors). Graphical presentations is preferred (Forest plots).
- Meta-analysis results: Combined effect estimate, confidence intervals, some measure of heterogeneity, results of bias assessment (preferably using graphical presentations, e.g. Funnel plot)
- Specification of the genes / polymorphisms (rs numbers) and rationale for selection of the specific polymorphisms
- Genotyping methods in each individual study
- Genotype characteristics (genotyping success rate, minor allele frequency, frequencies of genotypes, Hardy-Weinberg-equilibrium).
