  1. Data expressed as mean ± SD or number (percentage). Student’s t-test and Mann-Whitney U test were performed to compare the differences between the two groups, P < 0.05 was considered statistical significance. BMI, body mass index; AHI, apnea-hypopnea index; ODI, oxygen desaturation index; LSaO2, lowest saturation oxygen; MSaO2, mean saturation oxygen; ESS, epworth sleepiness scale; MoCA, montreal cognitive assessment; TS90, the total sleep time spent with oxygen saturation below 90%; TS90%, percentage of total sleep time spent with oxygen saturation below 90%.
