By fixing the segmentation model as 3D U-Net++, we used 1,136 (723 were positive) / 282 cases (154 were positive) to train / test the classification / combined model, the detailed data distribution was given in Tables S4, S5 and S6. Figure 2 (a) showed the receiver operating characteristic (ROC) curves of these four combined models. The "3D Unet++ -ResNet-50" combined model achieved the best area under the curve (AUC) of 0.991. Figure 2 The performance of the model improved steadily as the training data accumulated. In practice, the model was continually retrained in multiple stages (the average time between stages was about three days). Table S7 showed the training datasets we used in each stage.
