The statistical results of this study showed that Age, BMI, SBP, Duration, and HbA1C were independent influencing factors for VTDR in T2DM patients. Among them, the increase of SBP, Duration, and HbA1C was positively correlated with the onset of VTDR. It is worth noting that the increase of Age and BMI was negatively correlated with the onset of VTDR.Regression analysis in this study showed an OR for Age of 0.954 (95% CI: 0.940-0.969, The results of this study showed an OR for BMI of 0.942 (95% CI: 0.902-0.984, The logistic regression results showed an OR for SBP of 1.014 (95% CI: 1.007-1.022, As an indicator of cumulative microvascular system damage, the duration of diabetes has been shown to be positively correlated with the occurrence and development of DR and VTDR (The study found an OR for HbA1C of 1.325 (95% CI: 1.221-1.438, After integrating all independent factors, this study included five variables, Age, BMI, SBP, Duration, and HbA1C, in the construction of a column chart model. Discrimination analysis showed that the training set AUC was 0.7193 and the testing set AUC was 0.6897, which was lower than Ke, J.’s prediction model (However, this study still has limitations. Although this study developed a new nomogram for T2DM complicated with VTDR, the modeling and validation data were both from epidemiological data in the same region and did not conduct application experiments in the real world. Therefore, this model still needs further improvement and validation.
