Abbreviation: AHI: Apnoea hypopnea index, ESS: Epworth Sleepiness Scale, ODI: Oxygen desaturation index, SaO2: Mean Oxygen Saturation.
ESS, AHI, ODI and snoring are presented as median with interquartile range [25; 75%]. Mean SaO2 is presented as mean (SD). AHI≥5 and ≥15 are presented as percentage (number).
a From Epworth Sleepiness Scale, self-reported data.
b All-degree OSA, c Moderate-to-severe OSA
Statistics were performed using unpaired t-test or Mann-Whitney’s test, chi-squared test or Fishers exact test.
