What does this research mean for the field?

Long-term CPAP therapy reduces all-cause, cardiovascular, and pulmonary mortality in obstructive sleep apnea, but this survival benefit is strictly confined to patients with severe disease and those who achieve a good treatment response. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

This research aims to determine the impact of CPAP on long-term survival in patients with varying severity of obstructive sleep apnea.

Overview

Randomized trial reveals survival benefits of CPAP in severe obstructive sleep apnea, indicating importance of response quality.

Key Points

This research aims to determine the impact of CPAP on long-term survival in patients with varying severity of obstructive sleep apnea.
Single-centre cohort study of 4368 adults referred for polysomnography followed for 8–20 years.
Used cause-specific Cox and Fine–Gray competing-risks models and machine-learning classifiers to analyze mortality data.
Focused on a subgroup with apnea–hypopnea index (AHI) ≥ 15, N=2304.
CPAP reduced all-cause mortality (HR 0.75) and cardiovascular mortality (HR 0.75), but not in moderate OSA (HR 0.95).
Severe OSA patients benefited significantly, with an HR of 0.66.
Good responders had a 34% reduction in all-cause mortality (HR 0.66), while poor responders showed no significant reduction.
