, and 0.77 (95% CI 0.62 to 0.91), respectively. For the nomogram, the AUC for the training cohort, the internal validation cohort, and the external validation cohort was 0.86 (95% CI 0.77 to 0.95), 0.80 (95% CI 0.64 to 0.97), and 0.79 (95% CI 0.65 to 0.94), respectively. There were no statistical differences in the AUCs between the radiomics signature and the radiomic nomogram in the training cohort or the validation cohorts (all P0.05). The nomogram provides a novel strategy for determining the Ki-67 PI in predicting the
