Analysis of the factors for auto-adjusting positive airway pressure adherence in the patients with an AHI from 15 to 60/hr

^*Values are expressed as means±SD.

AHI: apnea-hypopnea index; ESS: Epworth sleepiness scale; minO₂: lowest point of O₂ desaturation; BMI: body mass index; effPr: effective pressure levels that eliminated 95% of the apnea and the hypopnea events; nMCA: minimal cross sectional area in the narrow side of the nasal cavity; wMCA: minimal cross sectional area in the wide side of the nasal cavity; sum MCA: summation of both MCAs; PTH: grade of the palatine tonsilar hypertrophy; Orophx: modified Mallampati grade of the oropharynx inlet.
