Receiver operating characteristic (ROC) performance assessment of the 17 readers for the conditions x-ray mammography (XRM)-alone and XRM + three-dimensional automated breast ultrasound (ABUS), as (a) histogram of the area under the ROC curve (AUC) values, (b) the AUC values per reader, and (c) histogram of the change in AUC, Δ(AUC). When referred to by number, readers are ordered throughout this report by increasing AUCXRM value. The error bars are ± standard error as given by the proper binormal ROC model.
