Time-dependent Cox proportional hazard models with and without adjustment for covariates. The crude model referred to time-dependent Cox proportional hazard models with no adjustment. Model 1 was adjusted for sex, age, and duration of diabetes. Model 2 was then further adjusted for education level, current smoking, regular drinking, BMI, blood pressure, hemoglobin A1c, serum cholesterol level, estimated glomerular filtration rate, and use of insulin.
