Values were presented by mean±SD/median [interquartile range] or n (%).
Statistically significant with p<0.05.
ESS: Epworth sleepiness scale, AHI: apnea-hypopnea index, ODI: oxygen desaturation index, TST: total sleep time, TAI: total arousal index, Min O2 sat: minimal oxygen saturation, PLMI: periodic limb movement index, OSA: obstructive sleep apnea, REM: rapid eye movement.
