  2. aA linear trend in the HR for each of the soft drinks categories was evaluated by including a continuous variable in the model representing the median values of each of soft drinks intake
  3. bAdjusted for baseline covariates: age centered, sex, total energy intake, physical activity, smoking status, family history of diabetes, and alcohol intake at baseline (tertiles), level of education
