Kaplan–Meier survival curves for outcomes among chronic obstructive pulmonary disease (COPD) patients without obstructive sleep apnoea (OSA) (COPD group), patients with COPD and coexisting OSA (overlap group), and patients with overlap syndrome treated with continuous positive airway pressure (CPAP) since enrolment (overlap with CPAP group). a) Survival and b) severe COPD exacerbation-free survival curves among the three study groups. The differences between curves from the COPD only and COPD with OSA treated with CPAP groups are statistically significant from the curve of patients with COPD and untreated OSA (p<0.001).
