CDCP1 and peripheral arterial disease: Among these, PAD exhibited a protective effect for 4 inflammatory proteins: CC motif chemokine 19 levels (OR, 0.714; 95% CI, 0.585 to 0.872; P=0.001), T-cell glycoprotein CD5 levels (OR, 0.818; 95% CI, 0.713 to 0.938; P=0.004), CUB domain-containing protein 1 levels (OR, 0.889; 95% CI, 0.809 to 0.977; P=0.015), and Signaling lymphocytic activation molecule levels (OR, 0.823; 95% CI, 0.693 to 0.978; P=0.027).
