  1. Normally distributed data (triglycerides, uric acid) were expressed as mean ± SD skewed data (including SBP/DBP, HDL-C, fasting glucose, metabolic score, VAI) were presented as median (interquartile range). Categorical variables were expressed as number (percentage). OSA: obstructive sleep apnea, SBP/DBP systolic/diastolic blood pressure, HDL-C high-density lipoprotein-cholesterol, VAI visceral adiposity index. *: if P < 0.05 between group 0 [AHI (0-5)] and group 1 [AHI(5-15)]; **: if P < 0.05 between group 0 [AHI (0-5)] and group 2 [AHI(15-30)]; ***: if P < 0.05 between group 0 [AHI (0-5)] and group 3[AHI(30-)]; ****: if P < 0.05 between group 1 and group 2; *****: if P < 0.05 between group 1 and group 3; ******: if P < 0.05 between group 2 and group 3
