Assessing the discriminative performance of the nomogram and comparison with other predictive models. The nomogram showed a significantly higher discriminative power than the radiomics signature and the radiologic model for the prediction of microvascular invasion in the training dataset (A), but did not differ in the test dataset (B). The calibration plots demonstrate that the nomogram-predicted probabilities were consistent with actual MVI incidence in the training (C) and test (D) datasets.
