The Editorial Office may request a copy of the ethical approval documentation.

Patient identity and confidential personal information must be adequately protected. Authors should not include identifiable information unless appropriate consent has been obtained.

9. Clinical Trials

Clinical trials should be appropriately registered where required by applicable standards and should provide the relevant registration information in the manuscript.

Authors should follow recognized clinical-trial reporting standards appropriate to the study design and provide sufficient methodological information for evaluation.

10. Statistical Analysis

Statistical methods should be described clearly and should be appropriate for the study design and type of data.

Authors should report, where applicable:

  • Statistical tests used.
  • Sample size considerations.
  • Measures of uncertainty.
  • Confidence intervals.
  • Exact or appropriately reported p-values.
  • Statistical significance criteria.
  • Software used for analysis.

Statistical conclusions should not exceed what is supported by the data.

11. Tables and Figures

Tables and figures should be numbered consecutively and cited in the main text.

Each table and figure should have a clear title or legend and should be understandable without requiring excessive reference to the main text.

Authors should ensure that:

  • Data are accurate and consistent with the manuscript.
  • Figures are of suitable quality.
  • Tables do not unnecessarily duplicate information in the text.
  • Appropriate permissions are obtained for previously published material.
  • Images do not contain unnecessary patient-identifying information.

Any manipulation of images must comply with accepted standards of research integrity and must not misrepresent the underlying data.

12. References

Individuals who contributed to the work but do not meet authorship criteria may be acknowledged where appropriate.

Changes to authorship after submission require appropriate justification and agreement from all affected authors.

14. ORCID

Authors are encouraged to provide their ORCID iD during submission. ORCID identifiers assist with accurate attribution of scholarly work and help distinguish researchers with similar names.

15. Funding Statement

All sources of financial support for the research should be disclosed.

The funding statement should identify the funding organization and, where applicable, grant or award information. If the research received no external funding, authors should state this clearly.

16. Conflict of Interest

Authors must disclose any actual, potential, or perceived conflict of interest.

Conflicts may include financial relationships, employment, consultancy, institutional interests, personal relationships, intellectual property interests, or other circumstances that could influence the research or its interpretation.

If there is no conflict, authors should provide a clear statement indicating that the authors have no conflict of interest.

Where applicable, authors should provide a statement explaining whether supporting research data are available and, if so, where and under what conditions they can be accessed.

Authors should respect participant confidentiality, legal restrictions, institutional policies, and ethical requirements when sharing research data.

18. Plagiarism and Similarity Screening

Authors must ensure that submitted manuscripts are original and properly acknowledge the work of others.

The journal may screen submissions using Turnitin or another appropriate similarity-detection and research-integrity tool.

Authors are encouraged to conduct a similarity check before submission and correct inappropriate text overlap, missing attribution, or other originality concerns.

The similarity percentage alone does not determine whether plagiarism has occurred. The nature and context of detected similarities will be considered.

Suspected plagiarism, duplicate publication, fabrication, falsification, or other research misconduct may be investigated in accordance with the journal's publication-ethics procedures and relevant COPE guidance.

19. Cover Letter

  • Any additional information the Editor should consider.

20. Peer Review

Manuscripts that pass initial editorial screening may be sent for external peer review.

The journal follows a single-blind peer-review process, in which reviewer identities are kept confidential from authors.

Reviewers assess manuscripts for scientific quality, originality, methodology, ethical compliance, statistical validity, clarity, and relevance.

The Editor-in-Chief or an authorized editor retains final responsibility for the editorial decision.

Possible decisions include:

  • Accept
  • Minor Revision
  • Major Revision
  • Reject

21. Reviewer Comments and Revision

When revisions are requested, authors should provide a detailed point-by-point response to reviewer and editorial comments.

Authors should clearly indicate the changes made in the revised manuscript and explain any reviewer recommendation that has not been adopted.

A revised manuscript may be returned to the original reviewers for further assessment.

22. Publication Ethics

The journal is committed to responsible scholarly publishing and follows relevant principles and guidance from organizations including the Committee on Publication Ethics (COPE) and, where applicable, the International Committee of Medical Journal Editors (ICMJE).

The journal may investigate allegations involving:

  • Plagiarism
  • Duplicate or redundant publication
  • Fabrication or falsification
