Evaluation of the predictive power of the seven DGF definitions for three-year GL(a) and death-censored GL(b) by a receiver operating characteristic (ROC) curve analysis using multivariate logistic regression models adjusting for donor age, cold ischemia time, HLA mismatch, donor hypertension history and donor terminal sCr. All DGF definition ROC curves were compared with each other via DeLong’s test. The AUCs of different DGF models declined from the top to the bottom as well as from the left to the right. Values and colored boxes in the grid represent the P-values of DeLong’s test. Blue shading represents the significance of the difference between ROC curves
