Fig. 2From: High prevalence of peripheral arterial disease (PAD) in incident hemodialysis patients: screening by ankle-brachial index (ABI) and skin perfusion pressure (SPP) measurementRelationship between ABI and SPP. ABI and SPP significantly and positively correlated (r = 0.311, p = 0.006). Dotted lines indicate the cutoff values of ABI and SPP. Note that SPP varied from abnormally low levels to normal levels in normal ABI valuesBack to article page
