AWC: waist circumference; NC: neck circumference; BMI: body mass index; AHI: apnea-hypopnea index; Minimum SaO2: the lowest oxygen saturation recorded during sleep; mean SaO2: the average oxygen saturation recorded during sleep; SaO2 ≥ 90 (% TST): the amount of total sleep time spent at ≥90% saturation; ESS: Epworth sleepiness scale.
