Example
A team conducting a systematic review on the effectiveness of exercise in managing knee osteoarthritis performs a quality appraisal of each included study using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist. This allows them to rate the methodological quality of the studies, identify any potential biases, and weigh the reliability of the evidence before drawing conclusions.
