ß, Standardized coefficient beta; CI, Confidence interval, FMD_sys [%], flow-mediated dilatation in systole adjusted for age, sex and baseline diameter at systole; BMI, Body mass index; LDL, low density lipoprotein; HDL, high density lipoprotein.

Model 1: FMDsys, Flow-mediated dilatation adjusted for baseline diameter at systole, age and sex as corvariates; n = 70, R² = 0.098, F_(13,57) = 0.479, p = 0.928.

Model 2: FMDsys, Flow-mediated dilatation adjusted for baseline diameter at systole, age sex, systolic blood pressure and BMI as covariates; n = 70, R² = 0.077, F_(11,59) = 0.449, p = 0.926.
