  • 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.
