Data are presented as means ± standard deviations, percentage (number). *A 1-way analysis of variance was applied to compare the means among the severity groups. AHI = apnea-hypopnea index, BMI = body mass index, HDL-C = high-density lipoprotein cholesterol, LDL-C = low-density lipoprotein cholesterol, OSA = obstructive sleep apnea, SaO2 nadir = oxygen saturation nadir, TC = total cholesterol, Tg = triglycerides.
