The aim of the PRISMA Statement is to help authors improve the reporting of systematic reviews and meta-analyses.
PRISMA can also be used as a basis for reporting systematic reviews of other types of research, particularly evaluations of interventions.
PRISMA may also be useful for critical appraisal of published systematic reviews, although it is not a quality assessment instrument to gauge the quality of a systematic review.
The PRISMA Statement consists of a 27-item checklist and a four-phase flow diagram. It is an evolving document that is subject to change periodically as new evidence emerges. In fact, the PRISMA Statement is an update and expansion of the now-out dated QUOROM Statement.
