Nomogram of DFU risk in diabetic patients with ASO of lower extremities. The red points in the figure represent the actual values of each index of a patient. The patient’s CRP was 50 mg/L, BMI was 24, diastolic blood pressure was 95 mmHg, he smoked about 10 cigarettes a day, was 84 years old, did not use insulin, had three lower leg arteries occlusion, had diabetic nephropathy, had a history of hypertension, and had no history of coronary heart disease. The final score was 469 points. The probability of DFU occurrence is 0.828. * represents the significance of the factor’s contribution to the model.
