The results of polysomnography.

Polysomnography	Mean ± SD	Median; (minimum–maximum)
AHI index (𝑛/h)	37.2±21.7	34 (6–108.1)
Mean SaO2 (%)	92.1±4.3	93 (75–97)
ODI index (events/h)	32.4±26.5	22.7 (0.8–104.0)
The lowest SaO2 (%) >2 sec (%)	73.1±16.1	79 (0–93)
Epworth score	12.1±6.1	13 (1–26)

Results are presented as mean ± SD and median (minimum–maximum).
AHI: apnea hypopnea index; SaO₂: oxygen saturation; ODI index: oxygen desaturation index.
