In the group who did not complete the study, the site of upper airway collapse was determined in three subjects who did not undergo a control study with their MAD, and the success rate was established in the four subjects who had no flow-limited twitches but had a control study. Values are given as the mean±SD.
AHI, apnoea–hypopnoea index; BMI, body mass index; SDB, sleep-disordered breathing.
