Manuscripts should be prepared with the following segments:

Cover letter should contain the rationale for performing the study and a statement that the article will not be submitted to another journal until the reviewing process has been completed. Moreover, authors should indicate whether they have published or submitted any related papers on the same study.

Title page should include the title of the study and names of the authors (with an email address) with their affiliations, as the first page of the manuscript. The complete mailing address, telephone number, and email address of the corresponding author should be mentioned.

Abstract should be less than 300 words. It should be structured under appropriate headings, and should be concise and comprehensible to readers. Keywords are used for indexing purposes; three to five keywords should be selected from the Medical Subject Headings (MeSH).

Introduction should cover a short background of former studies, refer to potential gaps in the literature, and should specify the aim of the study.

Methods should indicate, evidently, the stepwise approach taken to acquire the data, including the statistical analysis. It should mention the inclusion and exclusion criteria and should be preferably presented in chronological order. For reports of randomized clinical trials (RCTs), the authors should refer to the CONSORT statement. Reporting guidelines would help authors present a high-quality study and deliver all required information and evidence. The EQUATOR Network website can assist authors in following these guidelines.

Results should be presented in chronological order in the text, tables, and illustrations. Tables and figures must be cited in the order in which they appear in the text. Figures must have captions presented in a separate section with all abbreviations expanded. Tables must have a title and a footnote with all abbreviations expanded. Ensure all figures and tables have been cited in the text. Do not present tables with information repeated from the text of the paper. Figures should be provided only if they add further information. High-resolution figures (600 dpi) should be presented in the TIFF format. If you have reused or adapted figures, tables, or sections of text from papers published elsewhere, please approach the copyright owner and obtain their permission to re-use those elements.

Discussion should challenge the outcomes of the research with other publications in the literature in the format of arguments and counterarguments. The limitations and strengths of the study and the implications of the findings for future research or clinical practice should be presented.

Conclusions should present the final outcomes and brief recommendations that have been reached through the study. Of note, conclusions should not overstate and/or overreach the results.

Ethical declaration comprises ethical approval and conflict of interest, which should be reported.

Funding resources and Acknowledgments should be clearly declared in all submissions.

References should comply numerically in the order of citation in the text. We follow the Vancouver style, as outlined in the PubMed style.

It should be noted that if AI software like ChatGPT has been utilized to assist in any part of the manuscript, then it should be undoubtedly acknowledged in the manuscript and during the submission. The AI software does not meet the authorship criteria and is unable to accept responsibility and accountability for the research outcome therefore it is impossible to be listed in the author list.
