  • Data are presented as the fraction (%) or mean±SD.

  • a P values for binary data were generated from logistic regression for repeated measures using generalized estimating equations and taking into account the nested correlation induced by kidney laterality within donor (5). P values for parametric data were generated from a signed rank test on the matched case-control differences for clustered data (6). See Supplemental Table 5 for details.

  • b 0, none; 1, mild; 2, moderate; 3, severe.
