# Risk of Bias Assessment SOP

Conduct structured risk-of-bias assessment for individual studies using the appropriate validated tool (RoB 2.0, ROBINS-I, QUADAS-2, PROBAST, or Newcastle-Ottawa Scale).

## When to Use

- During quality assessment of each included study
- When deciding sensitivity analysis groupings
- When assessing GRADE certainty (risk of bias domain)

## Input

- `study_metadata`: Study characteristics, methods description, and results
- `study_design`: The study design (RCT, non-randomized, diagnostic, prediction model, observational)

## Output

Domain-level risk-of-bias judgments with supporting rationale for each signaling question.
