The PRISMA approach (Preferred Reporting Items for Systematic reviews and Meta-Analyses) is a widely recognized framework designed to improve the transparency and quality of systematic reviews and meta-analyses. It focuses on standardizing the reporting process, ensuring that studies are clear, comprehensive, and allow for replication.
Key Elements of PRISMA:
- Checklist: A 27-item checklist that ensures systematic reviews include key sections such as objectives, eligibility criteria, information sources, study selection, and results, among others.
- Flow Diagram: A flowchart that depicts the selection process of studies, starting from identification to final inclusion, highlighting the reasons for exclusions.
- Protocol Registration: Encourages researchers to register their review protocols in databases like PROSPERO to prevent duplication and enhance transparency.
- Updated Guidelines: The PRISMA statement has been updated periodically, with the most recent version being PRISMA 2020, reflecting modern practices in systematic review and meta-analysis.
