PRIMARY outcome

Timeframe: The entire study period (baseline and up to one-year)

Population: The intervention patients had polysomnography at baseline (n=102) whereas control patients either had polysomnography as part of usual care (n=7) or at the end of the study as part of the study protocol (n=85). The n=7 patients who had polysomnography as part of usual care were included in the analysis for this outcome.
