  1. These models were derived using a two-fold cross-validation approach in each randomly selected dataset and in the full cohort. Basic models included age and sex only. Full models for all-cause mortality included age, sex, coronary artery calcified plaque, urine albumin:creatinine ratio, diabetes duration, current smoking, educational attainment, insulin use, and waist hip ratio. Full models for CVD mortality included age, sex, coronary artery calcified plaque, urine albumin:creatinine ratio, history of CVD events, and diabetes duration. P-values for comparing the predictive power of the basic model with the full model are listed
