**Figure 4.** (**A**) Distribution of the number of selected deficits for the best FIs in each iteration among the 10 *genetic algorithm* cycles; (**B**) mean AUC and 95% confidence intervals in the prediction of 3-year and 6-year mortality in the whole population and in sex- and age subgroups (calculated in the complete dataset) for 100 randomly generated FIs including 40 deficits (mean AUC for ga-FI, calculated in the complete dataset, shown in red); (**C**) mean AUC in the prediction of 3-year and 6-year mortality in the whole population and in sex- and age subgroups (calculated in the complete dataset) for more than 2000 randomly generated FIs including 25-108 deficits (mean AUC for ga-FI, calculated in the complete dataset, shown in red) – boxplots show median and 2^{nd} and 3^{rd} quartiles of mean AUC for FIs with similar number of deficits.
