Mean areas under the receiver operating characteristic curves (AUCs) of the clinical, radiomics and combined models calculated from 100 iterations for the training set. The Kruskal-Wallis test was used to compare the overall difference among mean AUCs, and the Mann-Whitney U test was used to make pairwise comparisons between pairs of interest. Bonferroni correction was used for multiple comparisons. The combined model incorporating the clinical and radiomics features of contrast-enhanced mammography showed the highest mean AUC (0.934±0.030), followed by the radiomics (mean AUC =0.921±0.031, adjusted P<0.001) and clinical models (mean AUC =0.907±0.036, adjusted P<0.001).
