Figure 4. Prediction model performance. (A) Competing risk analysis for time to transplant stratified by availability of potential living donor for patients with Prediction score low vs. high on derivation set; interaction p < 0.0001. (B) Competing risk analysis for time to transplant stratified by availability of potential living donor for patients with Prediction score low vs. high on validation set; interaction p = 0.05. (C) Prediction Model area under curve on derivation set (0.82). (D) Prediction Model area under curve on validation set (0.84).
