Fig. 1

Median net benefit among 100 test subsamples, based on the resampling procedure, which was the same for each of the seven selected threshold probabilities. The solid line shows the logistic regression model, and the dot-dashed line shows the classification and regression tree (CART) model. The harm-to-benefit ratios are rounded to one decimal place (Inf = infinity, expressing an infinite harm to missing any true positive subject in the entire population)
