*
Renal disease defined as GFR < 60.
Data shown as mean +/− standard deviation, median [interquartile range], or N(%). P-values for continuous variables are from an t-test for normally distributed variables, a Kruskal Wallis test for non-normal data. Categorical variable p-values are from a chi-square test for homogeneity.
