Primary outcome results. Adjusted treatment effects (CPAP change minus standard care change) for ESS, and percentage risk of fatal cardiovascular event within 5 years
| Standard care/CPAP (N) | Adjusted treatment effect (95% CI) | p Value | |
|---|---|---|---|
| ESS | 171/170 | −2.0 (−2.6 to −1.4) | <0.0001 |
| 5-year risk of fatal vascular event (%) | |||
| Primary analysis | 156/154 | +0.1 (0.0 to +0.2) | 0.070 |
| Sensitivity analysis (ignoring smoking changes) | 156/154 | +0.1 (0.0 to +0.1) | 0.19 |
