Estimation of the statistical significance in the difference between the FROC performance of the FFDM CAD system and that of the SFM CAD system (a) for both benign and malignant cases, and (b) for malignant cases only, in the test subsets. The cluster-based test FROC curves with the FP cluster rates obtained from the test set with MCCs were compared
