Lagged Monthly Duration of CPAP Use | 25-Month Outcome (407 events) | 12-Month Outcome (246 events) | 6-Month Outcome (138 events) | 3-Month Outcome (99 events) |
---|---|---|---|---|
Unadjusted | 0.98 (0.96–0.99) | 0.95 (0.92–0.99) | 0.84 (0.77–0.93) | 0.90 (0.75–1.08) |

Values are presented as unadjusted and adjusted HRs (95% CI). *25-month outcome model adjusted for cataracts, congestive heart failure, chronic kidney disease, hypertension; 12-month outcome model adjusted for age, congestive heart failure, chronic kidney disease; 6-month outcome model adjusted for age, congestive heart failure; 3-month outcome model adjusted for age, atrial fibrillation, chronic kidney disease. **P = .02. CI = confidence interval, CPAP = continuous positive airway pressure, CV = cerebrovascular, HR = hazard ratio, OSA = obstructive sleep apnea.
