From: Evaluations of the uptake and impact of the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) Statement and extensions: a scoping review

Reporting guideline Year published Scope of reporting guideline
PRISMA 2009 Reports of systematic reviews and meta-analyses, primarily of randomised trials that evaluate health care interventions [11,12,13,14,15,16,17,18,19,20,21,22,23].
PRISMA-Equity 2012 Reports of systematic reviews and meta-analyses with a focus on health equity, defined as the absence of avoidable and unfair inequalities in health [24,25,26].
PRISMA-Abstracts 2013 Abstracts for all types of systematic reviews, but the emphasis is on systematic reviews of evaluations of interventions where one or more meta-analyses are conducted [27].
PRISMA-Network Meta-Analysis 2015 Reports of systematic reviews that address networks of multiple treatment comparisons [28].
PRISMA-Individual Participant Data 2015 Reports of systematic reviews and meta-analyses of individual participant data. Developed primarily for reviews of randomised trials, but many items apply to other contexts, including reviews of diagnosis and prognosis [29].
PRISMA-Protocols 2015 Protocols for systematic reviews and meta-analyses that summarise aggregate data from studies, particularly those which evaluate the effects of interventions [30, 31].
PRISMA-Harms 2016 Reports of systematic reviews and meta-analyses assessing adverse events (as either a primary or secondary outcome) that are reported in prospective interventional studies or observational studies (with or without a comparison group) [32].
PRISMA-Complex Interventions 2017 Reports of systematic reviews and meta-analyses of complex interventions. Complex interventions are defined as interventions that have ‘multiple components (intervention complexity) and complicated/multiple causal pathways, feedback loops, synergies and/or mediators and moderators of effect (pathway complexity)’ [33, 34].
