The proportion excess lost determined 1month, 3months, 6months 1year post OS. Non-parametric analyses performed; p <0.05 considered significant. Results 1,673 cases, mean (SD) age 47.6 (12.5) years, majority female (1,276, 76.3%), 58% identified Caucasian. Within this number, 92 candidates (n=50, 3%) recipients (n=42, 2.5%). older [51.5 (10.8) years vs 47.3 (12.6) P = .0008], had body [124.4 (22.5) kg 126.0 (27.2) kg, .8271] lower mass index [42.6 (5.7) kg/m2 45.1 (8.1) kg/m2, .0046] compared having transplant.
