^aCox proportional hazards model. ^bOrdinary least-squares regression model. ^cCompeting-risks regression model with mortality as a competing risk. ^dStatistically significant difference relative to “R nonobese, D obese” group. ^eStatistically significant difference relative to “R obese, D nonobese” 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, b = unstandardized coefficient, SHR = subhazard ratio, and CI = confidence interval.
