Changing of sensitivities and specificities of three ML models with the increasing of predictive thresholds. 3 ML models with higher Youden index (RF, GBDT and XGBoost) than the proposed model were selected. Results in training and test data were shown in upper and lower figures respectively. For each figure, thresholds with higher specificities than the proposed model were marked with pink, and with higher sensitivities were marked with blue
