  • Data are % for categorical variables and mean (SD) for continuous variables. Data on clinical measurements and comorbidities were complete for >80% of the population and demographic data were complete.

  • 1P value for difference between populations with and without diabetes.

  • 2Due to outliers, we defined the mean (SD) of serum creatinine among the central 0.95 of the population, with creatinine defined as ≥0.6 and ≤13.7.

  • 3Disability defined as needing assistance in activities of daily living.
