| Diabetes | 1.08 | 1.03 to 1.14 | 0.003 |
| Year of transplant | 1.04 | 1.03 to 1.05 | <0.001 |
| Recipient age (per year) | 1.03 | 1.03 to 1.03 | <0.001 |
| HLA mismatch | 0.94 | 0.91 to 0.97 | <0.001 |
| Donor age of >50 years | 0.92 | 0.86 to 0.98 | 0.006 |
| Expanded criteria donora | 0.92 | 0.87 to 0.97 | 0.001 |
| Induction immunosuppression | 0.90 | 0.85 to 0.96 | 0.001 |
| Peak PRA of >20% | 0.87 | 0.81 to 0.94 | <0.001 |
| Male gender | 0.78 | 0.75 to 0.82 | <0.001 |
| African-American race | 0.60 | 0.57 to 0.64 | <0.001 |
The following values are included in the model but not significant: dialysis vintage, delayed graft function, hypertension, ischemic heart disease, congestive heart failure, chronic obstructive pulmonary disease, cancer, tobacco use, rapamycin at discharge, donor type, cold ischemia time >24 hours.
a
Expanded criteria donor indicates donor age of >50 years with history of two of the following (stroke, hypertension, creatinine >1.5 mg/dl) or donor age >60 years.
