CRP and peripheral arterial disease: Compared with patients with normal ABI, those with ABI-defined PAD were older (<i>p</i> = 0.014) and had significantly higher prevalence of diabetes mellitus (<i>p</i> = 0.033), longer PD vintage (<i>p</i> = 0.036), higher fasting glucose (<i>p</i> = 0.005) and C-reactive protein (<i>p</i> = 0.003) levels, and lower SePP concentrations (<i>p</i> < 0.001).
