 The Prisma statement is a reporting guideline designed to improve transparency of systematic reviews, SRs, and meta-analyses. It provides guidance on how to report the methods used in conducting the review, as well as the results of the review. Nine extensions to the original Prisma statement have been published since it was first released in 2009, and eight more are currently under development. A scoping review was conducted to assess the uptake and impact of the Prisma statement and extensions. Studies evaluating the adherence of SRs to the Prisma statement and extensions were also identified and synthesized. The results showed that while there has been an increase in the number of SRs that adhere to the Prisma statement, there is still room for improvement. Furthermore, few studies have evaluated the effectiveness of the Prisma extensions or strategies to increase their use. This article was authored by Matthew J. Page and David Moer.
