Total number of participants (N) was 44 children. Age, BMI-z, and PSG parameters were not distributed normally, and therefore median and interquartile range are provided. Data in the table are presented as median (IQR) or N (%). AutoCPAP, auto-titrated continuous positive airway pressure, BMI-z = modified body mass index z-score (obese, BMI ≥ 95%), CAHI = central apnea-hypopnea index, OAHI = obstructive apnea-hypopnea index, PSG = polysomnogram.
