Disease duration(months)	Mean (95% CI)	3.25 (2.96, 3.54)
Polysomnography variables
Mean SaO2	(%)	95.33±2.41
AHI		33.25±24.86
min Sao2	(%)	74.87±12.62
Percentage of SaO2<90%	(%)	10.24±8.79
The data of the clinical variables and demographic characteristics are expressed as the mean±standard deviation (SD) for continuous variables when the data were normally distributed, as a 95% confidence interval (CI) when the data had a skewed distribution, or counts (percentages) for discrete variables.
