Plagiarism

According to the World Association of Medical Editors, plagiarism is described as

“…the use of others' published and unpublished ideas or words (or other intellectual property) without attribution or permission, and presenting them as new and original rather than derived from an existing source. The intent and effect of plagiarism are to mislead the reader as to the contributions of the plagiarizer. This applies whether the ideas or words are taken from abstracts, research grant applications, Institutional Review Board applications, or unpublished or published manuscripts in any publication format (print or electronic).”

In order to prevent plagiarism, it is advised for authors to have their manuscripts screened for plagiarism using software such as iThenticate, before submission for publication. Any plagiarism detected before or after publication will be addressed promptly by the editorial board.

Author name should be listed in First Name – Middle Name – Surname.

Reporting Guideline and Article Types

Each article submitted must be prepared according to guidelines and/or checklists based on its type, defined by the EQUATOR Network. https://www.equator-network.org/reporting-guidelines/

Formatting 

Style  

Text should be 1.5-spaced. The typeface should be Times/Times New Roman or similar serif typeface. Body text size should be no smaller than 10 pt and no larger than 12 pt.  Page size should be international A4 size (210 × 297 millimeters). Include page numbers in the manuscript file.

Title

The full title should be specific, descriptive, concise, and comprehensible to readers outside the subject field. Authors should include the species or model system used (for biological papers) or the type of study design (for clinical papers).

Authors and Affiliation

 All author names should be listed in the following order: First names, middle names (or initials, if used), and last names (surname, family name), followed by medical and/or highest academic degrees (eg, MD, Ph.D.). Each author should list an associated department, university, or organizational affiliation and its location, including city, state/province (if applicable), and country. Other parties who contributed to the scientific paper that did not meet the criteria for authorship can be listed in the Acknowledgement section.

When a large group or center has conducted the work, the author list should include the individuals whose contributions meet the authorship criteria defined above, as well as the group name. Authors should also disclose whether they had any writing assistance.

One author should be designated as the corresponding author, and his or her email address should be included on the manuscript cover page. This information will be published with the article when accepted.

Abstract

The abstract should be no more than 350 words, summarizing the problem being considered, how the study was performed, the salient results, and the principal conclusions. Specific instructions regarding abstract structure are often included in the relevant reporting guidelines checklist.

Introduction/Materials and Methods/Results/Discussion and Conclusions

The overall structure of your manuscript text should be in compliance with the corresponding reporting guideline. For example, a CONSORT compliant manuscript should include the following sections, as defined by the CONSORT checklist:

• Introduction
• Methods
• Results
• Discussion
• Other Information

Statistical Analysis

In the Methods section:

• Identify the statistical tests used to analyze the data and the determined P value that was taken to indicate a significant difference.
• Cite only textbooks and published article references to support your choices of tests.
• Identify any statistics software used. (List software name, version, and company in parentheses in the text, not in the reference list.)

In the Results section:

• Report actual P values rather than thresholds: not just whether the P value was above or below the significant-difference threshold. Example: write "P = 0.18", not "P > 0.05" or "P = NS."
• P should be expressed to 2 digits for P ≥ 0.01 because expressing P to more than 3 digits does not add useful information. If P < 0.001, it should be expressed as P < 0.001, rather than P < 0.0001 or P = 0.00001 for example. In certain types of studies, it may be important to express P values to more significant digits. Please consult the AMA Manual of Style for further direction.

Original Article

Original articles must have a maximum of 300 characters for structured abstracts and 3,500 characters for the article, excluding abstract, references, tables, and figure legends. The number of references should be no more than 50 and the number of figures, tables, and graphs should not exceed 8 in total.

Clinical Trial: an experimental study assessing the effect of 2 or more interventions. Reporting should follow the CONSORT flowchart matching the study design. For non-randomized trials involving habit or behavioral interventions, follow the TREND guidelines. 

Decision Analysis or Cost-Effectiveness Analysis: a study analyzing the optimal choice of clinical care by projecting the consequences of different medical care options. The report should follow the Second Panel on Cost-Effectiveness in Health and Medicine (Sanders et al. JAMA. 2016;316[10]: 1093-1103) to report economic evaluations of health interventions.

Diagnostic Study: A study that compares the performance of 2 or more diagnostic tests or strategies. Authors should follow the STARD guidelines.

Observational Study: Studies that observe patients who are exposed to certain potential risk factors or interventions, where researchers do not assign the interventions to the study’s subjects. This includes cohort, case-control, and cross-sectional studies. Authors should follow the STROBE guidelines with respect to their study designs.

Prognostic Study: A study that estimates the risk of a certain clinical endpoint associated with potential risk factors or predictors in a defined period of time. Authors should follow the TRIPOD guidelines.

Systematic Review or Meta-Analysis: A systematic review is an appraisal of current evidence in a certain field, using an explicit protocol to identify, appraise, and synthesize the studies of a similar question. Meta-analysis further quantifies the result of a systematic review. Authors should use the PRISMA flow diagram to report the study yield and selection.

Case Report

A case report presents an interesting, rare, and/or novel clinical case regarding newly described clinical presentation, diagnostic dilemma, or treatment responses that need further insight into the underlying mechanism. Limited to 1,500 words and requiring an unstructured abstract (150-200 words). The reference list should be no more of 20 in total and tables/figures should be a maximum of 2 in total. Authors should follow the CARE guidelines when applicable.

Evidence-Based Case Report: An evidence-based case report (EBCR) is a case report from which the author formulates a structured clinical question. This question generates key terms that can be used for yielding articles from an evidence database. After the relevant evidence has been identified and appraised, clinician informs a management plan for the patient based on the result and the clinician’s clinical experiential knowledge.

Review Article

Also known as a narrative review, this article explores clinical, translational, or basic science topic of interests. The article should be comprehensive, clinically relevant, and balanced. Basic science articles should discuss the relevance of cellular or biomolecular aspects to clinical diagnosis, prognosis, or treatment. The article should consist of up to 4000 words, including 150-200 words of unstructured abstract. The reference list should be no more than 100. Authors are encouraged to use figures, tables, and boxes up to 8 in total.
