BMI = body mass index, BP = blood pressure, FPG = fasting plasma glucose, HbA1c = glycated hemoglobin

HOMA-R = homeostasis model assessment ratio, HDL-C = high-density lipoprotein cholesterol

LDL-C = low-density lipoprotein cholesterol, Hb = hemoglobin, BNP = brain natriuretic peptide

LVEF = left ventricular ejection fraction, AHI = apnea-hypopnea index, ODI = oxygen desaturation index

SpO₂ = peripheral capillary oxygen saturation
