Using a genetic algorithm to derive a highly predictive and context-specific frailty index

Figure 2. Receiver-Operating-Characteristics Curve and Areas Under the Curve (AUC) for the prediction of 3-year and 6-year mortality obtained for the ga-FI and c-FI in the test sample. Abbreviations: 95% CI = 95% confidence intervals; ga-FI = best genetic algorithm-derived Frailty Index; c-FI = clinically generated Frailty Index.
