Abbreviations: HR; hazard ratio; IRR, incidence rate ratio; OR, odds ratio; CLDKT, compatible living donor kidney transplantation; ILDKT, incompatible living donor kidney transplantation.

Bold indicates P < .05.

^aOverall: weighted analyses (i.e., wIRR, wOR, wHR).

^bCLDKT/ILDKT: adjusted analyses (i.e., aIRR, aOR, aHR).

^c p for interaction compares CLDKT vs. ILDKT.

^dDid not achieve convergence for CLDKT and ILDKT estimates.
