  1. N = 232; 25 graft loss, no missing variables.
  2. The following variables were tested in the univariable model but not included in the multivariable model: CMV-positive donor, CMV-positive recipient, presence of HLA antibodies, donor age, donor gender, any HLA-A, HLA-B or HLA-DR mismatch, type of calcineurin inhibitor (tacrolimus versus CsA), cold ischemia time and presence of acute rejection episodes 90 or 180 days after transplantation.
