  1. CVD cardiovascular disease, DCSI diabetes complications severity index, IQR interquartile range
  2. *Categorical variables were evaluated for association using the Chi squared test; continuous variables were tested using the Mann–Whitney U test
  3. aDCSI complications identified using ICD-9 codes as outlined by Young et al. [19]. For each complication, scale 0 = no abnormality, 1 = some abnormality, 2 = severe abnormality, as classified by Young et al.
  4. bCategory reflects DCSI-specific cardiovascular complications: atherosclerosis; other ischemic heart disease; angina pectoris; other chronic ischemic heart disease; myocardial infarction; ventricular fibrillation, arrest; atrial fibrillation, arrest; other atherosclerotic cardiovascular disease; old myocardial infarction; heart failure; atherosclerosis, severe; aortic aneurysm/dissection
