Author Guidelines for Review Articles

Accepted Types of Review Articles

  1. Systematic Reviews
    Rigorous reviews conducted using predefined criteria and a transparent methodology to address a specific research question.
  2. Meta-Analyses
    Quantitative reviews that statistically combine findings from multiple studies to produce robust, pooled estimates.
  3. Scoping Reviews
    Exploratory reviews that map existing evidence, clarify key concepts, and identify knowledge gaps, without assessing study quality in-depth.

Reviews such as narrative reviews, commentaries, mini-reviews, or opinion pieces are not accepted.

General Requirements

Study Recency

  • Include only peer-reviewed studies published within the past 5 years.
  • Older studies may be referenced for historical context but must not be included in the data synthesis.

Minimum Literature Coverage

  • A minimum of 150 to 200 relevant peer-reviewed studies must be included in the literature review.
  • Clearly document the number of included studies in your PRISMA flow diagram.

Compliance with Reporting Guidelines

All submitted review manuscripts must adhere to internationally recognized reporting standards based on the type of review being conducted. Systematic reviews are required to follow the PRISMA 2020 guidelines. Meta-analyses must comply with PRISMA along with any relevant PRISMA extensions specific to their methodology. For scoping reviews, authors must follow the PRISMA-ScR guidelines. In every case, a completed checklist corresponding to the appropriate guideline must be submitted alongside the manuscript.
