    Snippet: Detailed information was presented on the Result E2, Table E3 and Figure Figure E5 . The results showed that the detection performance was not sensitive to the confidence score as long as the cutoff for confidence score was in a reasonable range (Table E4 ). The detection model achieved F1 score 0.742 under confidence cutoff 0.1. We further used the annotated lesions to train and evaluate the model. Trinary scheme (with AUC 0.95) performed better.....
    Document: Detailed information was presented on the Result E2, Table E3 and Figure Figure E5 . The results showed that the detection performance was not sensitive to the confidence score as long as the cutoff for confidence score was in a reasonable range (Table E4 ). The detection model achieved F1 score 0.742 under confidence cutoff 0.1. We further used the annotated lesions to train and evaluate the model. Trinary scheme (with AUC 0.95) performed better than the Plain scheme (with AUC 0.93) ( Figure E6 ). More performance measures can be found in Table E5 . Two experienced specialists classified the lesions on which two schemes made very different predictions (with probability difference no less than 0.5) ( Figure E7 ). 366 (or 174) out of 540 NCP lesions were identified by Trinary (or Plain) scheme correctly. Detailed analysis showed that the Plain scheme tend to yield unreasonably high or low probability of lesion predictions depending on the lesions from centers in the training set or not. The results indicated the Trinary scheme was more consistent with specialists than Plain scheme on the lesion level classification.
