Figure 1 Endothelium-dependent flow-mediated dilation (FMD) of the brachial artery during reactive hyperemia (endothelium-dependent vasomotion) is significantly higher in subjects with no evidence of aortic valve sclerosis (AVS) than in patients with AVS. Data are expressed as the median value (25% and 75% and outliers, in a "box-and-whiskers" plot). *p < 0.002.
