Cox proportional hazards models were used to determine the risk of graft failure (death or retransplant) in the lowest tertile SE group (low SE group) compared with the remaining 2 of 3 patients (controls). The 2 groups were similar with respect to age, gender, diagnosis, and year of transplant. White race was less frequent in low SE group (64% versus 90%,\n            <jats:italic>P<\/jats:italic>\n            =0.001). Graft failure occurred in 46 transplant recipients (40 deaths, 6 retransplant). Low SE group (hazard ratio 2.4, 95% CI 1.3 to 4.3) and nonwhite race (hazard ratio 2.7, 95% CI 1.4 to 5.2) were both associated with higher risk of graft failure. In a multivariable model controlling for diagnosis and pretransplant support, race, and low SE position (hazard ratio 2.0, 95% CI 1.0 to 3.7,\n            <jats:italic>P<\/jats:italic>\n            =0.04) remained associated with graft failure.
