Manuscript preparation

1. Types of manuscripts

We consider the following article types:

Types Word count Content No. of References
Original Article >3000 Original Articles include randomized controlled trials, intervention studies, studies of screening and diagnostic testing, outcome studies, cost-effectiveness analyses, case-control series, and surveys with high response rate. >20
Review >5000 Review articles that summarize the current state of understanding of a topic. >50
Case Report >1000 Case Reports should detail new, interesting, or unusual cases. These cases will very often be unique, describing a diagnostic or therapeutic challenge, and will always present a new perspective to readers. Cases with clinical significance or implications will be given priority. >10
Editorial >1000 Editorials are nearly always solicited, although unsolicited editorials may occasionally be considered. >10
Letter to Editor >500 Letters to Editor include the contents and references. >5
Commentary >1000 Commentaries are always solicited by the editors. These manuscripts should include relevant background information, comments on the paper, areas that need further investigation, and future directions. The relevant manuscript should be included in the reference list. >5

The word count excludes the abstract, figures, tables, and references.

2. General format of manuscripts

The manuscript should be written in concise English, and should generally be organized as follows:


Please provide a concise and specific title (no more than 12 notional words) that clearly reflects the manuscript’s content. And a running title (3-6 words) should also be provided in a manuscript.

Authors and affiliation

• All authors who played significant roles in the research should be listed in the manuscript.

• Include all authors’ full names. Once accepted, authors cannot be added or deleted, and the order cannot be changed without the written consent of all authors.

• Provide full affiliation information (complete name of the department, institution, city, postcode, province/state, and country) for all authors.

• Indicate a single corresponding author. The name, title, institution, address, telephone number, and e-mail of the corresponding author should be given, to ensure prompt communication.


• The abstracts of original articles (maximum 200 words) should be structured under four separate headings (Aim, Methods, Results, Conclusion).

• Reviews and Case Reports should generally have unstructured abstracts (200 and 100 words, respectively).

• Editorial, Commentary and Letter to Editor which manuscripts do not require an abstract.

• The first person (I, we) and citations should not be used in the abstract. Abbreviations should be used sparingly and defined at their first use.


Authors should supply 3–8 relevant key words that describe the subject of their research, in order to improve its visibility.


The information in this section should always be referenced. It should indicate the broad context and should include a brief review of the key literature related to the study.


The Methods should provide enough detail for the research to be reproduced elsewhere; protocols for new methods should be included, but well-established methodological procedures may simply be referenced. Full details of methods used should be included in the manuscript rather than in a supplementary file. If methods used are as per a published paper, the corresponding reference should be cited in the Methods section.

Ethics and Patient consent

A statement on ethics committee permission and patient consent must be included in the Methods section (If the experiment involves the relevant content, please see 5. Ethics approval and 6. Patient consent, below).

• Quantify findings and present them with appropriate indicators of measurement error or uncertainty (such as confidence intervals) whenever possible.

• Authors should report losses to observation (e.g., dropouts from a clinical trial).

• Specify the statistical methods used to analyze data that are summarized in the “Results” section.

• Avoid non-technical use of technical terms in statistics, such as “random” (which implies a randomizing device), “normal,” “significant,” “correlations,” and “sample.”

• Define statistical terms, abbreviations, and all symbols used.

• Specify the computer software used. Use upper-case italics to denote P values (i.e., P < 0.048).

• For all P values include the exact value and not less than 0.05 or 0.001.

• Mean differences in continuous variables, proportions in categorical variables, and relative risks including odds ratios and hazard ratios should be accompanied by their confidence intervals.s.


All the results, including those in all figures and tables, should be analyzed and explained precisely. In addition, this section should also include all primary and secondary outcome measures analyzed. The Results section should be written in past tense.

  • • With respect to prospective studies involving human participants, authors are also expected to cite approval from a regional/national/institutional or independent Ethics Committee or Review Board, regarding obtaining informed consent from adult participants and obtaining assent from children aged over 7 years participating in the trial.

  • • The age above which assent is required varies with regional and/or national guidelines and should be verified.

  • • Ensure confidentiality of subjects by avoiding mentioning participants' names, initials, or hospital numbers, especially in illustrative material (e.g., X-ray or other imaging films/clips/slides).

  • • For studies involving animals, authors should indicate whether an institution's or a national research council's guide, such as the guidelines issued by the Committee for the Purpose of Control and Supervision of Experiments on Animals (CPCSEA), or any national law on the care and use of laboratory animals, was followed.

  • • Evidence of approval by a local Ethics Committee (for both human as well as animal studies) must be supplied by the authors on demand.

  • • Animal experimental procedures should be as humane as possible, and the details of anesthetics and analgesics used should be clearly stated.

The article should include Title, Authors and affiliations, Abstract (unstructured, 200 words), Introduction, the main content (with appropriate headings), Conflicts of interest, Acknowledgments, and References. There should be a section describing the methods used for locating, selecting, extracting, and synthesizing data (these methods should also be summarized in the abstract).

Case Report

Headings in the main text of a Case Report should include Introduction, Case report, and Discussion. An unstructured abstract (100 words) is required.


Editorials are nearly always solicited, although unsolicited editorials may occasionally be considered. No abstract is needed.

Letter to Editor

A Letter to Editor includes the contents and references. No abstract is needed.


Commentary should include some relevant background information, comments on the paper, areas that need further investigation, and future directions. No abstract is needed. Authors should note that the manuscript you are commenting on should be included in the references.


Supplementary information (optional)

Submission checklist

The revised version of a manuscript should be submitted online in a manner similar to that used for the initial submission. When submitting a revised manuscript, contributors are requested to include the referees’ remarks along with point-by-point responses; these should be placed together at the beginning of the revised file, immediately ahead of the revised article. In addition, contributors are expected to mark as underlined or colored text the revisions that they have made to their article.

  1. 1. The type of manuscript and word count should conform to the corresponding instructions for that manuscript type.

  2. 2. The author details should be checked for all authors, to ensure that all the information provided is correct and is suitable for publication.

  3. 3. The main text of the article from the Abstract through the References (including tables) should be in this file. Use .docx/.doc files. Do not zip the files. Limit the file size to 4 MB. Do not incorporate images. If file size is large, graphs can be submitted separately to reduce the size of the article file.

  4. 4. The formats, size, and definition of images and tables should be checked carefully. Tables in the manuscript should be in editable format, rather than as images. For images/figures, PowerPoint presentations, and additional material, the maximum file upload size is 10 MB.

  5. 5. Legends to the figures/images should be included at the end of the article file.

  6. 6. References: Check the order, number, and formats of the references carefully.

  7. 7. Registration number in case of a clinical trial and where it is registered (registry name of the registry and its URL).

  8. 8. If the manuscript was presented as a contribution to a Meeting, the organization, place, and exact date on which it was read should be indicated.

    A full statement describing all submissions and previous reports that might be regarded as replicate or overlapping publications of the same or very similar work should be sent to the editor. Any such work should be clearly referred to specifically, and referenced in the new paper.


Submitting a revised manuscript
