Systematic review
The full PRISMA 2020 sequence: PICO → search → dedupe → dual screen → RoB → synthesis → GRADE.
When you have time and want Cochrane-level rigourRapid review
Cochrane Rapid Reviews Methods Group (Garritty 2021) — single-reviewer screening with verification, streamlined extraction, primary-outcome RoB.
When you have a deadline (decision in days/weeks)Prognostic review
PROGRESS framework + PICOTS, CHARMS extraction, QUIPS / PROBAST, GRADE-for-prognosis (Foroutan 2020).
When the question is about prognostic factors or prediction modelsNetwork meta-analysis
Multi-treatment comparisons: transitivity, consistency, node-splitting, SUCRA ranking, CINeMA confidence.
When the question compares more than two interventionsDiagnostic test accuracy
QUADAS-2 appraisal, bivariate / HSROC pooling, threshold-effect detection, GRADE-DTA.
When the outcome is a diagnostic test's sensitivity / specificityNot sure which one fits? Most clinical-effectiveness reviews start with systematic review. For a guideline urgency, see rapid review. Each workflow page links the same allmeta tools — picking the wrong one isn't a hard error.
