Table 4 Relative risk of poor outcome loss in KT recipients. KT with MRA was not associated with increased risks of vascular and urologic complications, delayed graft function, rejection, graft loss, and death when compared with KT with SRA.

| KT – kidney transplant; IPTW – inverse probability of treatment weights; OR – odds ratio; CI – confidence interval; SRA – single renal artery; MRA – multiple renal arteries; HR – hazard ratio. | ||||||||
