Adjusted for baseline values of the variables analyzed and age, sex, BMI, AHI, and FEV1. *P < .05 intragroup difference (3 months–baseline). **P < .01 intragroup difference (3 months–baseline). AHI = apnea-hypopnea index, BMI = body mass index, BPAP = bilevel positive airway pressure, CI = confidence interval, CPAP = continuous positive airway pressure, ESS = Epworth Sleepiness Scale, FEV1 = forced expiratory volume in 1 second, NS = not significant, PSQI = Pittsburgh Sleep Quality Index, SD = standard deviation, SF-36 = Medical Outcome Survey Short Form-36.
