PRISMA Statement
PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) is the standard guideline for reporting systematic reviews and meta-analyses of healthcare interventions.
1Detailed Explanation
The PRISMA statement was published in 2009 and updated in 2020 (PRISMA 2020). It includes a 27-item checklist and a flow diagram (previously called QUOROM). Key elements include: abstract structure, introduction (rationale and objectives using PICO), methods (eligibility criteria, information sources, search strategy, study selection, data extraction, risk of bias assessment, synthesis methods), results (study selection, study characteristics, risk of bias, synthesis results), and discussion (summary, limitations, conclusions). Extensions exist for network meta-analyses, individual participant data meta-analyses, and scoping reviews.

3Why It Matters in Research
PRISMA is the accepted standard for reporting systematic reviews and meta-analyses. Most medical journals require PRISMA compliance, and many require registration in PROSPERO.
