JBI revised critical appraisal tool for RCTs
This checklist helps researchers assess the reliability and quality of randomized controlled trials by evaluating the risk of bias. It ensures that studies included in systematic reviews are scientifically sound and trustworthy.
At a glance
Use when
Conducting systematic reviews that include randomized controlled trials and require standardized, reliable risk of bias assessment.
Avoid when
Assessing non-randomized study designs or when detailed trial methodology is poorly reported.
Inputs
Full text of a randomized controlled trial, including methods, results, and supplementary materials.
Outputs
Assessment of risk of bias across key domains, supporting inclusion or exclusion decisions in systematic reviews.
How it works
The revised JBI critical appraisal tool for randomized controlled trials was developed by the JBI Effectiveness Methodology Group in 2023 to align with current risk of bias science. It provides a structured set of criteria to assess methodological quality and risk of bias in RCTs, with detailed guidance on interpretation and application, including illustrative examples. The tool updates the previous version to reflect best practices in systematic reviewing and methodological rigor.
- HTA domains
- Clinical Effectiveness, Safety
- Assumptions
- The tool assumes that sufficient methodological detail is reported in the study to permit reliable judgment of bias risk.
- Strengths
- Developed through a rigorous, evidence-informed process; aligned with current methodological standards; includes clear guidance and examples for consistent application.
- Limitations
- Relies on accurate and complete reporting in primary studies; may require expert judgment for borderline cases.
- Also known as
- JBI RCT critical appraisal tool, JBI risk of bias tool for RCTs, Revised JBI Appraisal Tool for RCTs
