Performance comparison of radiomics in the unsure group (likely benign and likely malignant) to expert radiologists and the effect of encountering the prediction model. Supplementary Figure 4. Performance comparison of radiomics in the unsure group (likely benign and likely malignant) to expert radiologists plotting the 95% confidence interval AUC. Supplementary Table 1. Performance comparison of radiomics and the two expert radiologists. Supplementary Table 2.
