Manuscripts Preparation

Types of manuscripts

Original ArticleOriginal 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.
ReviewReview articles that summarize the current state of understanding of a topic.
Case ReportCase Reports should detail new, interesting, or unusual cases. Cases with clinical significance or implications will be given priority.
EditorialEditorials are nearly always solicited, although unsolicited editorials may occasionally be considered.
Letter to EditorLetters to Editor include the contents and references.
CommentaryCommentaries 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.


General formats of manuscripts

1. Title

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.

2. Authors and affiliations

• 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.

3. Abstract

• 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 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.

4. Keywords

Supply 3-8 relevant key words that describe the subject of their research, in order to improve its visibility.

5. Text

(1) Original Article

The main content of Original Articles should include four sections: Introduction, Methods, Results, Discussion.


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.


This section should provide enough details 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.

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).

Selection and description of participants

Selection of observational or experimental participants (patients or laboratory animals, including controls) should be clearly described, including also eligibility and exclusion criteria and a description of the sources.

Technical information

• Identify the methods, apparatus (list manufacturers’ names and locations in parentheses), and procedures in sufficient detail to allow other workers to reproduce the results.

• Give references to established methods, including statistical methods (see below); provide references and brief descriptions for methods that have been published but are not well known; describe new or substantially modified methods, give reasons for using them, and evaluate their limitations.

• Identify precisely all drugs and chemicals used, including generic name(s), dose(s), and route(s) of administration.

• Reports of randomized clinical trials should present information on all major study elements, including the protocol, interventions (e.g. methods of randomization, concealment of allocation to treatment groups), and the method of masking (blinding).


• 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.


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 discussion should be concise and tightly worded. It should include paragraphs on the generalizability, clinical relevance, strengths, and limitations of the study. And the main findings of the study should be summarized in the section.

(2) Other article types

For Review, generally section titles depend upon the topic being reviewed. The article should include introduction and the main content (with appropriate headings). 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). For Case Report, headings in the main text should include Introduction, Case report, and Discussion. There are no special format rules for the text of Editorial, Commentary, Letter to Editor.
