^aCox proportional hazards model. ^bStatistically significant difference relative to “R nonobese, D obese” group. All models are adjusted for D and R gender, D and R race, D and R age, R diagnosis, D and R diabetes history, D and R serum creatinine, D and R bilirubin, R INR, albumin, and MELD score at LT, and D SGOT and SGPT, acute rejection, PVT, and cold ischemia time.

LT = liver transplantation, R = recipient, D = donor, HR = hazard ratio, and CI = confidence interval.
