17. Supplements

Purpose

The Pakistan Journal of Gastroenterology (PJG) may publish supplementary issues to disseminate high-quality scientific information on specific themes, conference proceedings, clinical guidelines, consensus statements, educational materials, or other scholarly content that is consistent with the Journal's aims and scope. Supplementary publications must maintain the same standards of scientific quality, editorial independence, and publication ethics as regular issues.

This policy is developed in accordance with the recommendations of the Committee on Publication Ethics (COPE), the International Committee of Medical Journal Editors (ICMJE), and the World Association of Medical Editors (WAME).

  • Special thematic issues.
  • Educational reviews.
  • Research collections.
  • Workshop reports.

  • Ethical compliance.

17.5 Conflict of Interest

Authors, Guest Editors, reviewers, and Editorial Board members involved in a supplement must disclose all relevant financial and non-financial conflicts of interest.

Conflict of Interest declarations will be published where appropriate in accordance with the Journal's Conflict of Interest Policy.


17.6 Identification of Supplements

Each supplementary issue will be clearly identified on the Journal website and in the published issue.

The supplement will include information regarding:

  • Supplement title.
