Have You Seen PRISMA?

Systematic reviews and meta-analyses are needed to synthesize evidence regarding clinical questions. Unfortunately the quality of these reviews varies greatly. As part of a movement to improve the transparency and reporting of important details in meta-analyses of randomized controlled trials (RCTs), the QUOROM (quality of reporting of meta-analysis) statement was developed in 1999.[1] In 2009, that guidance was updated and expanded by a group of 29 review authors, methodologists, clinicians, medical editors, and consumers, and the  name was changed to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses).[2] Although some authors have used PRISMA to improve the reporting of systematic reviews, and thereby assisting critical appraisers assess the benefits and harms of a healthcare intervention, we (and others) continue to see systematic reviews that include RCTs at high-risk-of-bias in their analyses. Critical appraisers might want to be aware of the PRISMA statement.
