Fig. 4

Application of selected probability thresholds on test database. This figure shows population distributions by risk group with pie charts and performance metrics for two risk threshold models. The left panel uses thresholds of ≤ 0.1 for low risk and ≥ 0.5 for high risk, while the right panel uses ≤ 0.2 for low risk and ≥ 0.4 for high risk. Bar charts display accuracy, true negatives, and false positives for each group
