Risk-Adjusted Analysis of Relevant Outcome Drivers for Patients after More Than Two Kidney Transplants

Figure 1

(a) The ROC-curve for age in years is shown for the prediction of mortality during follow-up. The area under the curve (AUROC) indicates potential prognostic value (AUROC = 0.723; 95% CI: 0.588–0.857). Multivariate Cox regression revealed age as a significant independent risk factor for mortality during follow-up. The cut-off value for age in years at last transplant chosen with the best Youden index for the prediction of mortality was 43 years. (b) Survival of patients who are ≤ 43 years old is significantly superior as compared to those who are older than 43 years at the time of their last kidney transplant (; Kaplan-Meier survival analysis, log rank test).
