  1. aValues are mean ± standard deviation. Units are mg/dL for HDL, LDL, and TG intercept; mm Hg for SBP intercept; mg/dL per visit for HDL, LDL, and TG slope; mm Hg per visit for SBP intercept.
  2. bModel included sex, baseline age, diabetes status, and baseline BMI as time-invariant covariates, and number of cigarettes smoked per day as a time-varying covariate.
  3. cModel identical to BMI time-invariant model, except BMI was treated as a time-varying covariate.
