Long-term CPAP Effect with Obstructive Sleep Apnea: a Telemedicine-based

After the participants enter the trial, participants underwent two-night home PSG to confirm the diagnosis of OSA. Once AHI ³15/h is confirmed, participants undertake baseline evaluation within two weeks which included standard questionnaire, eating behavior, 3-day photograph-based intake recording, and 7-day sleep log, 24-hr ambulatory blood pressure, 7-day Actiwatch and Actigraph, 2-morning attention and memory task at home environment. The BMR, BC, Proton Magnetic Resonance Spectroscopy (1H-MRS), and blood sampling are conducted in the morning when patients was fasting at hospital.

Once participants complete the baseline evaluation, they are randomly allocated to the usual care or auto-CPAP treatment (AirSense™ 10 Autoset™, ResMed Inc., Australia) for 48 weeks. The randomization is generated by the staff of the Department of Biostatistics independent of subject enrolment. A block-randomized assignment with a block size of four is used. Consecutive patients are assigned to the allocation according to the randomization schedule by the study nurse.

After randomization, participants had virtual visits at 4th, 12th, 24th, and 48th week and are evaluated with the same measurements as pre-randomization after complete the trial.

Once the patients complete the trial, they receive the standard treatment of OSA and are followed every 24 to 48 weeks for five years.
