  • Data were presented as median (minimum values – maximum values). *P<0.05, compared with pre-CPAP data.

  • Defined as the number of respiratory events per 1 hour (events/hour), as in snoring index (events/hour).

  • **Kolmogorov-Smirnov test indicated that both RDI levels of pre-CPAP and those of post-CPAP showed normal distributions, and thus the data of paired t-test were shown.

  • CPAP, continuous positive airway pressure; ESS, Epworth Sleepiness Scale; MCS, mental component summary; PCS, physical component summary; RDI, respiratory disturbance index; SDB, sleep disordered breathing.
