a structured set of evidence-based guidelines created to enhance the clarity, completeness, and transparency of how systematic reviews and meta-analyses are reported in research publications. These guidelines help authors provide enough information for readers, reviewers, and policymakers to assess the quality of the review and its findings. They typically include a checklist and a flow diagram outlining how studies were identified, screened, and included.
Abbreviation: PRISMA
Example
A research team conducts a systematic review and meta-analysis on the effectiveness of biologic treatments for rheumatoid arthritis. To ensure their article is clear and comprehensive, they follow the PRISMA checklist and flow diagram to describe how studies were searched, selected, and synthesized, which increases the credibility and reproducibility of their findings.
