Accuracy was assessed through BIRADS ratings and DMIST likelihood scores, comparing two commonly used indicators of accuracy between mammography plus AWBU versus mammography alone: areas under the curve (AUC) and figures of merit (FOM). The FOM incorporates information from each reader on the region of suspected malignancy, as well as their confidence level in the finding, incorporated in an AUC. Because it includes both confidence level and location accuracy, the FOM is more powerful than AUC in detecting differences between techniques. We include both analyses, as described below:
