OSA, obstructive sleep apnea; BMI, body mass index; AHI, apnea/hypopnea index; ODI, oxygen desaturation index; AI, arousal index; SPO2, pulse oxygen saturation; TST, total sleep time; REM, rapid eye movement; NREM, nonrapid eye movement; TG, triglycerides; TC, total cholesterol; LDL, low-density lipoprotein; HDL, high-density lipoprotein; FBG, fasting blood glucose; ESS, Epworth Sleepiness Score. aAdjusting for age, BMI, gender, and waist-to-hip ratio. ∗P < 0.05, the results are statistically significant.
