Figure 1. Alternative free-response ROC curves for SFM and FFDM plotted by using a rating scale from 0-100. The x-axis scale is the probability of a false-positive finding being called with the two screening views of a given breast. This is analogous to the false-positive rate in a standard ROC experiment. There is no difference in the areas under the curves. The area under each curve is 0.76.
