Prediction of delayed graft function using different scoring algorithms: A single-center experience

Figure 1 Receiver operating characteristic curves to evaluate the prognostic capacity of cold ischemia time, the delayed graft function risk calculator, the Jeldres scoring system[10] and the DGFS scoring system[11] to predict delayed graft function. The cold ischemia time (purple-line): Area under ROC curve (AUC) = 0.52. The DGF risk calculator (green-line) proposed by Irish et al[9]: AUC = 0.69. The scoring system (blue-line) proposed by Jeldres et al[10]: AUC = 0.54. The DGFS scoring system (red-line) proposed by Chapal et al[11]: AUC = 0.51. ROC: Receiver operating characteristic; CIT: Cold ischemia time; DGF: Delayed graft function.

Figure 2 Calibration plot of: The delayed graft function risk calculator (Irish et al[9]), the Jeldres scoring system[10] and the DGFS scoring system (Chapal et al[11]) to predict delayed graft function. Patients were divided into 10 subgroups (deciles of increased DGF risk), based upon the risk prediction. Each figure plots the mean predicted probability (X-axis) of DGF against the observed prevalence of DGF (Y-axis) (Hosmer-Lemeshow). The P-values were 0.74 for the Irish score, < 0.05 for the Jeldres score and 0.02 for the Chapal score. DGF: Delayed graft function.

Figure 3 Correlation between the predicted delayed graft function probability according to the delayed graft function risk calculator (Irish et al[9]) and the presence or absence of delayed graft function. DGF: Delayed graft function.

Figure 4 Correlation between the predicted delayed graft function probability according to the Jeldres scoring system (Jeldres et al[10]) and the presence or absence of delayed graft function. DGF: Delayed graft function.

Figure 5 Correlation between the DGFS value (A: Y-axis) and the predicted delayed graft function probability according to the DGFS scoring system (Chapal et al[11]) (B: Y-axis) and the presence or absence of delayed graft function (A and B: X-axis). DGF: Delayed graft function.
