Percentage of patients recalled by non-professional subjects during D-type trials in Experiment 2. A, B Conditions in which the CAD system determined the given mammogram to be positive or negative for cancer (A, B, respectively). Note that the prominent effect of the five false alarm rate values (0.05, 0.25, 0.5, 0.75, and 0.95, in order) is especially apparent in panel B as a broadly repeating pattern of five bars starting from far left. The blue X symbols and line graphically denote the theoretically expected probabilities (also see x-axis labels). The cancer probabilities estimated by the same set of subjects during the paired E-type trials across the same conditions are shown in the same order in Fig. 3. See text for details
