Systematic Reviews

What is PRISMA?

Preferred Reporting Items for Systematic reviews and Meta-Analyses, or PRISMA, is an evidence-based minimum set of items to help authors improve the reporting of systematic reviews and meta-analyses. PRISMA is part of a broader effort, to improve the reporting of different types of health research, and in turn to improve the quality of research used in decision-making in healthcare.
