The number of transplantations having the characteristic described in column 1.
P values > 0.05 are underlined.
SGF was defined as not having DGF but serum creatinine on posttransplant day 5 > 3.0 mg/dL without dialysis. When values for serum creatinine were missing on day 5, an average of days 4 and 7 was substituted, or when day 4 was missing day 7 was substituted. Of the 918 (18.1%) SGF missing values, 884 were substituted. A missing value indicator for the remaining 34 missing included in the model was not statistically significant.
IF was defined as not having either DGF or SGF.
DGF was defined as the need for dialysis within the first week after transplantation. It was called short if only 1 or 2 dialysis treatments were required, and prolonged if 3 or more treatments were required.
