  • a Only primary variables of interest are presented. The model was adjusted for the following covariates: Recipient age, gender, race, body mass index (BMI), history of diabetes, history of hypertension, total duration of ESRD, cause of ESRD, mean and peak PRA levels, number of pretransplantation transfusions, total number of transplants, number of different RRT modalities used, donor type, donor age, gender, race, BMI, heart-beating or not, donor history of diabetes, cold ischemia time, and number of matched antigens.
