^*Full model also adjusted for: recipient attributes of race, sex, diabetes status, prior solid organ transplant, dialysis time, panel reactive antibody, hepatitis C serostatus, glomerulonephritis, polycystic kidney disease, congenital/reflex kidney disease, hypertensive kidney disease, and cytomegalovirus status; donor attributes of type (live, deceased versus extended criteria deceased), age, race (black versus other), and cytomegalovirus status; and allograft attributes of human leukocyte antigen mismatch.
