Fig. 3From: A new method for the assessment of endothelial function with peripheral arterial volumeSimilar to brachial artery FMD, the PAV index generally correlated with the numbers of CRFs (r = 0.53, P < 0.01 for FMD, r = 0.45, P < 0.01 for PAV). Values are expressed as the mean ± SDBack to article page
