Types of Manuscripts
The Editors will consider and publish the following:
Manuscripts describing original research must be no longer than 5,000 words (excluding references), abstract of 275 words, no more than 50 references, and a title with no more than 120 characters (excluding spaces). Please include all relevant portions of the Methods section, as well as all references, in the main manuscript. See Submission elements below. We encourage you to submit additional methodological details, nonessential figures or portions of your manuscript as supplementary material for online publication only. References cited in the main text may not be listed in the supplementary materials. The only references that may be listed in the supplement are those cited exclusively in the supplement. All submissions must adhere to the 50 reference limit.
Brief Reports describing novel observations should be no longer than 2,500 words, abstract of 275 words, and no more than 25 references. No more than 3 figures and tables.
Editorials are invited by the Editor or Associate Editors and should be no longer than 1,500 words (including references) and include no more than one figure or table and 10 references.
Reviews of both basic and clinical topics should be no longer than 5,000 words (excluding references). The reference list need not be exhaustive. While most reviews are invited by the Editors, authors interested in contributing reviews are requested to first contact the Editor or one of the Associate Editors with an outline of the proposed article.
Letters to the Editor may be subjected to peer review and undergo editing for clarity and brevity, and should be no longer than 500 words (including references) and include no more than 5 references and one figure.
Special Articles are on a variety of topics and may include AASLD practice guidelines, in-depth scientific reviews, and comments on social policy. It's recommended that the length of each article is kept within the 5,000 words (excluding references) but is also decided by the Editor on a case-by-case basis.
Consensus Reports should be no longer than 2,000 words and include no more than 9 references. Manuscripts that exceed the word limits listed above will be returned to the authors for shortening without a full review. Manuscripts that are redundant or contain extraneous material will be returned after a full review for shortening even if otherwise acceptable.
If the concept and idea for this study originated with anyone other than the senior or corresponding authors, please provide details in the manuscript cover letter. Specifically state in the cover letter whose idea the study was, especially if the idea came from someone who is not an author. If any of the authors were provided financial incentives or honoraria for their work on this manuscript, please provide details in the manuscript cover letter.
Submissions must include the following:
- Complete manuscript (title page, author information, abstract, and text) as one Microsoft Word document
- Tables submitted separately in one Microsoft Word document
- Figures submitted separately in TIFF format with a resolution of 300 dpi (dots per inch)
- Any material that could constitute prior or concurrent publication of similar data by any of the authors, including symposium proceedings, book chapters, invited papers, and the like.
- The names of reviewers whose expertise qualifies them to review the work
- A description of any commercial affiliation or consultancy of an author that could be construed as a conflict of interest
- An author agreement signed by every contributing author. It is assumed, however, that the corresponding author speaks for his or her coauthors and certifies that all listed authors participated meaningfully in the study and that they have seen and approved the final manuscript.
- Editorial formatting (use of italics, superscripts, Greek letter, etc.) should be consistent. Typographical formatting (column widths, type styles, etc.) should not be used. Text should be flush left; paragraphs should not be indented and should be separated by two hard returns. Do not use hard returns within paragraphs. Do not use the program's indenting or margin-setting features; these will be added during typesetting.
- Submissions may include the names of any reviewers the authors wish to exclude along with the reason for exclusion for the Editors to consider.
- Requests to exclude an Associate Editor can only be considered if a clear conflict of interest is explained in the cover letter.
All elements of a manuscript should be double-spaced, and all pages must be numbered in the upper right corner, starting with the title page. Manuscripts describing original research should contain, in this order, the following elements:
- Title. No more than 120 characters, not including spaces between words. The use of acronyms and abbreviations should be avoided. The species used for work with experimental animals must be indicated in the title.
- Author Names. The full name, e-mail, and institutional affiliation of all authors must be included. In a multi-authored work involving more than a single institution, indicate individual affiliation by means of a superscript Arabic number. Indicate a change of address similarly.
- Keywords. Five keywords that do not appear in the title itself.
- Contact Information. Name, address, telephone number, fax number, and e-mail address for the corresponding author.
- List of Abbreviations. Include the expansions and list in the order of their mention in the paper.
- Financial Support. List grants and other financial support.
Write as continuous text organized as background and rationale for the study, main results, and conclusions. Acronyms and abbreviations must be defined in the abstract to allow the abstract to stand alone. Do not exceed 275 words. The last section should start with “Conclusion:”
Do not include a heading. Provide the minimum background information that will orient the general reader.
Provide a level of detail such that another investigator could repeat the work; for methods that are used without significant modification, citation of the original work will suffice.
- Human Subjects. For reports of research using human subjects, provide assurance that (a) informed consent in writing was obtained from each patient and (b) the study protocol conformed to the ethical guidelines of the 1975 Declaration of Helsinki as reflected in a priori approval by the appropriate institutional review committee. Refer to individual patients by number, not by initials. Hepatology Communications will only accept papers for review from liver transplant centers that explicitly state that no donor organs were obtained from executed prisoners or other institutionalized persons. Papers without such explicit statements will be returned without review.
- Animal Experimentation. In studies involving animal experimentation, provide assurance that all animals received humane care according to the criteria outlined in the “Guide for the Care and Use of Laboratory Animals” prepared by the National Academy of Sciences and published by the National Institutes of Health (NIH publication 86-23 revised 1985).
Manuscripts that use mice and other in vivo experimental models should include the following information:
- Sex and age of mice (or other in vivo experimental models) for all the experiments;
- The genetic background(s) of the mice or other experimental in vivo models;
- For transgenic or genetic mouse models, whether the controls were sibling littermates or were purchased separately (if purchased separately, were the animals cohoused to minimize potential microbiome effects);
- Specifics of the animal diet composition;
- Whether mice were fasted (and for how long) or not before a challenge or assessment is carried out;
- Type of bedding, caging system, and enrichment used for housing the mice; and
- If interventions were done, were they done during the light or dark cycle.
- Genetic Sequence Data. In papers reporting a novel DNA or amino acid sequence, verify that the data have been or will be submitted either to GenBank or EMBL, and provide the accession number. This information need not accompany the initially submitted manuscript but must be available for inclusion in the final publication. Accession numbers appear as footnotes to the text or in the relevant figure legend. It is understood that authors publishing in Hepatology Communications will make cloned DNA, hybridomas, mutant animals, and other resources available to qualified investigators.
- Manufacturers. Include the names and locations (city and state or country) of manufacturers when mentioning proprietary drugs, tools, instruments, software, etc.
Randomized controlled trials should be presented according to the CONSORT guidelines (JAMA 2001;285:1987-1991 or http://www.consort-statement.org ). Authors must provide the CONSORT checklist (found at http://mc.manuscriptcentral.com/hep, under Instructions and Forms) with a diagram that illustrates the progress of patients through the trial, including recruitment, enrollment, randomization, withdrawal and completion, and a detailed description of the randomization procedure. Manuscripts that fail to comply with CONSORT guidelines or do not include the CONSORT checklist at the time of submission will not be reviewed for publication. All clinical trials should be registered in order to be published in Hepatology Communications.
All clinical trials should be registered in order to be published in Hepatology Communications.
Results and Discussion
These two sections must be separate. Present the major findings of the study in graphic form if practicable. Do not illustrate minor details if their message is conveyed adequately by simple descriptive text. Mention all tables and figures. In the discussion, concisely present the implications of the new findings for the field as a whole, minimizing reiteration of the results, avoiding repetition of material in the introduction, and keeping a close focus on the specific topic of the paper.
Number references in the order cited as Arabic numerals in parentheses on the line. Only literature that is published or in press (with the name of the publication known) may be numbered and listed; abstracts and letters to the editor may be cited, but they must be less than 3 years old and identified as such. Refer to only in the text, in parentheses, other material (manuscripts submitted, unpublished data, personal communications, and the like) as in the following example: (Chercheur X, unpublished data). If the owner of the unpublished data or personal communication is not an author of the manuscript under review, a signed statement is required verifying the accuracy of the attributed information and agreement to its publication. Use Index Medicus as the style guide for references and other journal abbreviations. List all authors up to six, using six and “et al.” when the number is greater than six. For all listed citations with two or more authors who share first authorship, Hepatology Communications stipulates those authors’ names to be in bold type. It is the authors’ responsibility to ensure that these names appear in bold in the reference section when submitting a manuscript. This allows giving due credit to joint first authors. Also, please include the phrase, “Author names in bold designate shared co-first authorship” at the end of the references section if you have citations that have joint first authors.
