Adherence to Continuous Positive Airway Pressure (CPAP) Treatment and the Risk of Recurrent Cardiovascular Events: A Meta-Analysis
Pooled resultResult — go to the resultHazard ratio 1.01 95% CI 0.87–1.17Authors' conclusion
Adherence to CPAP was associated with a reduced MACCE recurrence risk, suggesting that treatment adherence is a key factor in secondary cardiovascular prevention in patients with OSA.
Study context
- Population
- Adults with CVD and obstructive sleep apnea (OSA) (secondary prevention)Individual participant data (IPD) meta-analysis of SAVE, ISAACC, RICCADSA
- Participants
- 4,186 adults

- Outcome
- First recurrent MACCE
