Figure 3b:
Performance of CV19-Net. (a) Receiver operating characteristic curve of the total test data set (left) with 5869 chest radiographs and the probability score distribution (right). (b) Pooled performance of the three chest radiologists compared with CV19-Net for the 500 test cases. (c) Receiver operating characteristic curves of CV19-Net for different vendors (V1–V4) and hospitals (H01–H05) in the test data set. AUC = area under the receiver operating characteristic curve, COVID-19 = coronavirus disease 2019.
