Lower limb survival and overall survival based on the risk classification. We categorized the three groups according to the number of risk factors based on a Cox regression analysis. Patients with zero or one risk factor, two risk factors, and three or four risk factors were regarded as the low-risk, intermediate-risk, and high-risk groups, respectively. Lower limb survival and overall survival were significantly lower in the high-risk group than in the other groups.
