Interpreting systematic reviews involves understanding their methodology and the quality of evidence. Key elements to consider include:
- Risk of bias: Check if the review assesses the risk of bias in included studies. - Heterogeneity: Look for statistical measures like I² to gauge variability among studies. - Confidence intervals: Wider intervals indicate less precision in the estimated effect. - GRADE system: Some reviews use the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) system to rate the quality of evidence.
