overall review score: 4.5
score is between 0 and 5
The risk-of-bias (RoB) tool from Cochrane Collaboration is a standardized methodological instrument designed to assess the potential for bias in randomized controlled trials (RCTs). It guides systematic reviewers in evaluating the internal validity of included studies by examining various domains such as selection bias, performance bias, detection bias, attrition bias, and reporting bias. The tool aims to improve the transparency and consistency of bias assessment in systematic reviews and meta-analyses.
