Table 4.

Averages and standard deviations of c-indices from 10-fold cross-validation.

	MALEs		MACEs		MALEs + MACEs
	Avg. C-Index	Std. Dev. C-Index	Avg. C-Index	Std. Dev. C-Index	Avg. C-Index	Std. Dev. C-Index
Crude MCR model	0.54	0.009	0.63	0.02	0.54	0.009
Multivariate-adjusted MCR model	0.57	0.009	0.81	0.014	0.56	0.009
Traditional model	0.55	0.01	0.81	0.01	0.54	0.007

MCR: modified cumulative risk; MALEs: major adverse limb events; MACEs: major adverse cardiovascular events. Multivariate model adjusted by hyperlipidemia, smoking status, chronic obstructive pulmonary disease, chronic kidney disease, hemodialysis/peritoneal dialysis, creatinine, atrial fibrillation, immune-related disease, hemoglobin, cholesterol, low-density lipoprotein, high-density lipoprotein, triglyceride, and glucose levels.
