risk-of-bias
Assess risk of bias in research studies for systematic reviews. Use when: (1) Conducting systematic reviews, (2) Evaluating study quality, (3) GRADE assessments, (4) Meta-analysis planning.
When & Why to Use This Skill
The Risk of Bias Assessment skill is a specialized tool designed for researchers and academics to systematically evaluate the methodological quality and potential biases in scientific studies. By implementing industry-standard frameworks like Cochrane RoB 2, ROBINS-I, and QUADAS-2, it streamlines the critical appraisal process essential for systematic reviews, meta-analyses, and evidence-based medicine. This skill ensures rigorous evaluation of randomization, intervention deviations, and reporting integrity to determine the reliability of research findings.
Use Cases
- Systematic Reviews: Automate the evaluation of study quality and risk of bias for large sets of literature to ensure high-quality evidence synthesis.
- Meta-analysis Planning: Identify and exclude studies with high risk of bias to improve the statistical validity and reliability of pooled results.
- GRADE Assessments: Support the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) process by providing detailed bias analysis for evidence certainty.
- Clinical Guideline Development: Assist medical professionals in assessing the strength of clinical evidence before formulating healthcare recommendations.
- Peer Review Support: Help academic reviewers and editors quickly identify methodological flaws or reporting biases in submitted research manuscripts.

Risk of Bias Assessment Skill
Purpose
Systematically evaluate methodological quality and potential biases in research studies.
Tools by Study Design
RCTs: Cochrane Risk of Bias 2 (RoB 2) Non-randomized: ROBINS-I Diagnostic Studies: QUADAS-2 Prognostic Studies: QUIPS
RoB 2 Domains
Randomization Process
- Adequate sequence generation?
- Allocation concealment?
Deviations from Interventions
- Blinding effective?
- Adherence to protocol?
Missing Outcome Data
- Complete data?
- Appropriate handling?
Outcome Measurement
- Blinded assessment?
- Validated measures?
Selective Reporting
- All outcomes reported?
- Pre-registered?
Risk Levels
- Low: Minimal bias
- Some concerns: Potential bias
- High: Serious bias likely
Integration
Use with literature-reviewer agent for systematic quality assessment of included studies.
