↵^a Nonobese = BMI <30; obese = BMI ≥30. GFR calculated using the Modification of Diet in Renal Disease formula. Cr, creatinine.
↵^b Measured by ttest for continuous variables and the χ² test for categorical variables.
↵^c Comparisons between obese at donation and nonobese at donation groups.
↵^d Comparisons between nonobese at F/U and obese at F/U.
