Limitations
- 1 relevant study has unresolved authoritative design evidence and does not contribute to design-specific or RoB-specific claims.
- Evidence uses heterogeneous comparison contexts: baseline_within_group, unknown_unresolved, usual_care.
- 2 supporting studies have high, serious, critical, unclear, or unavailable risk-of-bias information.
