Data are presented as or (%), , or median (interquartile range, IQR), unless otherwise stated. OSA: obstructive sleep apnea; BMI: body mass index; CAD: coronary artery disease; SBP: systolic blood pressure; DBP: diastolic blood pressure; AHI: apnea-hypopnea index; ESS: Epworth Sleepiness Scale; MSaO2: mean oxygen saturation; lowest SaO2: lowest oxygen saturation; CT90: percentage of cumulative time with oxygen saturation below 90% during sleep time.
