-indices and calibration curves for the new model. 200 sample bootstrapped calibration plots for the prediction of 1–3-year renal survival are shown. The gray line represents the ideal fit while the black line represents practical fit. The -indices for 1-3 years were 0.80 (95% CI: 0.65-0.94), 0.86 (95% CI: 0.77-0.94). and 0.78 (95% CI: 0.55-0.97), respectively. Brier scores were 0.06 (95% CI: 0.04-0.09), 0.09 (95% CI: 0.05-0.13). and 0.16 (95% CI: 0.06-0.32), respectively.
