There are a number of reporting standards for systematic reviews. These can serve as guidelines for protocol and manuscript preparation, and journals may require that these standards are followed for systematic reviews.
Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) is an evidence-based minimum set of items for reporting in systematic reviews and meta-analyses. There are a number of extensions of the original PRISMA standards including PRISMA-P (an updated version of PRISMA) and PRISMA-IPD (for systematic reviews and meta-analyses of individual participant data).
An international standard for literature search reporting aligned with the PRISMA Statement to improve the quality and reproducibility of reported literature searches.
The EQUATOR Network gathers guidelines for reporting on different types of trials and research studies. Includes CONSORT, STROBE, PRISMA, MOOSE, RAMESES, and more.
The Methodological Expectations of Cochrane Intervention Reviews (MECIR) project aims to specify methodological expectations for Cochrane Protocols, Reviews, and updates of reviews on the effects of interventions, and to ensure that these methodological expectations are supported and implemented across The Cochrane Collaboration.
The Appraisal of Guidelines for Research and Evaluation (AGREE) Instrument evaluates the process of practice guideline development and the quality of reporting.
