Notes: CAI = CPAP adherence intervention; CDR-SOB = clinical dementia rating sum of boxes; CPAP = continuous positive airway pressure; SD = standard deviation; Q1 = first quartile; Q3 = third quartile; due to 3 missing values, N = 171 for CDR-SOB. Due to 10 missing values, N = 164 for nighttime sleep duration; except for CDR-SOB and nighttime sleep duration, N = 174 for all other variables.
