Note. MCI = mild cognitive impairment; +CPAP = Continuous Positive Airway Pressure adherent defined as mean use ≥ 4 hours/night; -CPAP = Continuous Positive Airway Pressure non-adherent defined as mean use <4 hours/night; HVLT = Hopkins Verbal Learning Test; DS = Digit Symbol; MoCA = Montreal Cognitive Assessment; ESS = Epworth Sleepiness Scale; ECog = Everyday Cognition; PE = parameter estimate; SE = standard error; 95% CI = 95% confidence interval.

^†Effect sizes generated from unadjusted general linear models for change from baseline to 1 year. The p-values are for comparisons between the +CPAP and -CPAP groups.
