Distribution of CAD recommendations, stratified by training for the prospective dataset. (A) Distribution of annotated (no. of lesions in x-axes) and detected (no. of detected lesions in y-axes) lesions. (B) Relative frequencies of different predictions from the CAD system. For both (A,B) the colors correspond to a classification relating to whether or not this recommendation would lead to a change in the diagnostic algorithm proposed to the patient.
