Supported Appraisal tools
Get started with AMSTAR 2, ROBINS-I, or RoB 2 today.
AMSTAR 2
Appraising the methodological quality of systematic reviews of healthcare interventions, including reviews that include randomized trials, non-randomized studies of interventions, or both. AMSTAR 2 is most useful when users need to decide how much confidence to place in the results of a published systematic review.
AvailableROBINS-I V2
Assessing risk of bias in the results of follow-up (cohort) studies that compare the health effects of interventions and were not assigned by randomization. ROBINS-I V2 is the recommended risk-of-bias tool for non-randomized studies of interventions in Cochrane systematic reviews.
AvailableRoB 2
Assessing risk of bias in the results of individual randomized controlled trials (RCTs) included in a systematic review or evidence synthesis. RoB 2 is the recommended risk-of-bias tool for randomized trials in Cochrane Reviews.
