Data are presented as mean ± SD, median (25%–75% IQR), or n (%). P values represent between-group comparisons using Fisher exact tests, Student t tests, or Mann-Whitney U tests. For a Fisher exact analysis of body weight status between participants with and without OSA, underweight and normal-weight participants and overweight and obese participants were grouped. Missing data included the following: body weight status (n = 1, non-OSA group); information regarding HTN treatment (non-OSA group: n = 2; OSA group: n = 1); diabetes (non-OSA group: n = 2); dyslipidemia (non-OSA group: n = 4; OSA group: n = 1); MetS (non-OSA group: n = 4; OSA group: n = 1); and HIV status (non-OSA group: n = 3). BMI = body mass index, CMR = cardiometabolic risk, CV = cardiovascular, DBP = diastolic blood pressure, HDL-C = high-density lipoprotein cholesterol; HTN = hypertension, IQR = interquartile range, LDL-C = low-density lipoprotein cholesterol, MAP = mean arterial pressure, MetS = metabolic syndrome, OSA = obstructive sleep apnea, SBP = systolic blood pressure, SD = standard deviation, SES = socioeconomic status, WC = waist circumference.
