Objective To analyze the influencing factors of type 2 diabetes mellitus complicated with nephropathy based on biochemical indexes and construct Nomogram prediction model. Methods The data of patients in the complication group and non-complication group were observed to analyze the relevant factors affecting type 2 diabetes mellitus complicating nephropathy; Nomogram prediction model was constructed and validated. Results Compared with patients in the non-complicated group, the patients in the complicated group had higher levels of BMI, disease duration, CysC, HbA1c, BUN, Cr, hs-CRP, UA, lower levels of FCP, HDL-C, UA, and a higher percentage of the presence of insulin resistance (P < 0.05); the AUC of BMI, disease duration, FCPCysC, HDL-C, HbA1c, BUN, Cr, and hs-CRP were 0.702, 0.696, 0.609, 0.690, 0.626, 0.806, 0.647, 0.607, 0.689, 0.655, respectively (P < 0.05); BMI, disease duration, HbA1c, UA, and insulin resistance were the patients with co-morbid nephropathy (P < 0.05); Nomogram model was constructed based on risk variables to predict the risk of comorbid ne-phropathy in patients with type 2 diabetes mellitus with a C-index of 0.753 (95% CI: 0.712-0.769), and the risk threshold of this model was > 0.15; Analysis of the ROC curve based on the validation set showed an AUC of 0.902 (0.844-0.960); H-L goodness-of-fit test showed: χ² = 14.918, P = 0.061 (P > 0.05). Conclusion BMI, disease duration, HbA1c, UA, insulin re-sistance are the influencing factors of type 2 diabetes mellitus patients with comorbid nephropathy, and the constructed Nomogram model has good predictive ability and clinical practical value. It helps to individualize and quantify the assessment of patients with comorbid nephropathy.
