  1. Bolded values indicate significant variables
  2. Parameter estimates, standard error (SE) and p values from sequential linear regression models are presented above. The model presented above is the final model and included baseline covariates: age at diagnosis, race, sex, diabetes type, duration of DM, heart rate and blood pressure, physical activity, lipids, BMI, HbA1c, LVM index and carotid femoral pulse wave velocity and adjusted for clinical site. All outcomes are log transformed for modeling
