  • Data are % for categorical variables and mean (SD) for continuous variables. Data on clinical measurements and comorbidities were available for >80% of the population and demographic data were complete. Only variables that were collected at each time point (2000, 2005, and 2010) were included.

  • 1All comparisons are P < 0.05.

  • 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.
