In a forward conditional multivariate Cox regression analysis, the factors which significantly contributed to predicting outcome independent of each other and confounders were CRP (HR 1.1; CI: 1.03–1.12; P = 0.04), the presence of peripheral vascular disease (HR 18.6; CI 1.9–180; P = 0.01), and serum albumin (HR 0.06; CI 0.005–0.77; P = 0.03). Here, ALB is linked to peripheral vascular disease.
