Baseline (A) demographic and (B) vascular characteristics of cross-sectional study population. Values are mean and standard deviation and p values are from paired t-tests. (FMD = flow-mediated dilation, FA = femoral artery, BA = brachial artery, BMI = body mass index, WSS = wall shear stress, SR = shear rate, PORH = post-occlusive reactive hyperaemia).
