  1. MAP (mean arterial pressure), calculated as MAP = SBP/3 + DBPx2/3 (SBP = systolic blood pressure, DBP = diastolic blood pressure), HR = heart rate, BMI = body mass index, Chol = cholesterol, LDL = low-density lipoprotein cholesterol, HDL = high-density lipoprotein cholesterol, CRP = C-reactive protein.
