(0.PSG): First-night polysomnogram without using any appliance so as the baseline severity of OSA to be determined.
(PSG.K1): The first week of control polysomnogram performed to group KW following 1-week insertion of the Klearway appliance.
(PSG.K2): Third control polysomnogram after one-month usage of Klearway appliance.
