Study Endpoints

Primary Endpoints

CPAP adherence
Daily over 3 months

Mean daily average of CPAP use over 3 months

Flanker inhibitory control and attention test
Baseline, 1-, 2- and 3-months

Executive function is assessed using the validated NIH Toolbox Cognition Battery's Flanker inhibitory control and attention test. In a Flanker task, participants are required to indicate the left-right orientation of a centrally presented stimulus while inhibiting attention to the potentially incongruent stimuli that surround it (i.e., the flankers, typically two on either side). Primary outcome is the overall percent of correct responses in incongruent trials.

Secondary Endpoints

Mean Epworth Sleepiness Scale score Scores
Baseline, 1-, 2-and 3-months
Mean Functional Outcomes of Sleep Questionnaire (FOSQ) short form score
Baseline, 1-, 2-and 3-months
Mean Insomnia Severity Index score (ISI) Scores
