Performance of collocation ranking: second benchmark. Subfigures 2a and 2b are based on the second benchmark. The abscissa shows the percentage of the population selected for prevention or surveillance efforts. The ordinate shows the ratio of the B2 of a given indicator and the B2 of the collocation indicator, that is, ordinate values >1 indicate that the collocation indicator performs better than the other indicator it is compared to. Subfigure 2a compares the B2 value of the 10th, 25th, 50th, 75th, and 90th percentile of 100,000 randomly selected subpopulations to the B2 of subpopulations selected by the collocation indicator. Subfigure 2b compares B2 of all indicators defined in the Methods section, as well as the optimal B2, to the B2 of the collocation indicator.
