“…The incidence of BCAR was defined in the study protocol as a secondary end point. Potential predictors for the occurrence of BCAR were evaluated based on previously reported literature (17)(18)(19). Thirteen variables were tested: baseline GFR, age, race, years since transplant, sex, history of rejection, initial CNI, use of steroids, azathioprine, MMF, mycophenolate sodium, sirolimus trough level and time-normalized trough sirolimus concentration (C min-TN ).…”
