In a univariate logistic regression analysis, T-Cho (OR, 1.017; 95% C.I., 1.001–1.033, p < 0.0332), LDL-C (OR, 1.027; 95% C.I., 1.007–1.048, p < 0.0077), non-HDL (OR, 1.018; 95% C.I., 1.002–1.034, p < 0.0263), diabetic retinopathy (OR, 3.913; 95% C.I., 1.143–13.397, p < 0.0298), and insulin treatment (OR, 6.313; 95% C.I., 1.635–24.377, p < 0.0075) were identified as predictive factors. This evidence concerns the gene INS and diabetic retinopathy.
