Prevalence is an important epidemiological metric that allows for the comprehension and comparison of health conditions across populations. Prevalence estimates are frequently synthesised in systematic reviews, which themselves are being published with increased frequency. Members of the Prevalence Estimates Reviews - Systematic Review Methodology Working Group, an international academic group which aims to develop and disseminate methods for systematic reviews and meta-analysis of prevalence, started developing this PRISMA extension for systematic reviews of prevalence. The group has already published a review showing that a high proportion of information remain unreported in this type of reviews, such as specification of a study protocol, presentation of the strength of evidence in the findings summary, or transformation methods for proportions results.
Considering that the evidence from the published review does not cover the period after the publication of PRISMA 2020, the group plans to conduct another review to identify systematic reviews of prevalence published from January 1st, 2023, onwards. The development team also declares that they will include members from the PRISMA Executive, who have expressed interest in participating in the project. They plan to publish the reporting guideline in 2025 as an open-access document.
