Performance comparison in AUC of GBM model for modality combinations of each testing set obtained by performing 100 iterations of data shuffling. AUC showed a statistically significant improvement in the modality combination that added image features compared to when only demographic characteristics were used (p-value < 0.05). There was a statistically significant improvement in the AUC when adding MRI image features to the model compared to using the demo + A modality combination (p-value < 0.05). However, there was no statistically significant difference in the AUC between the model using the demo + AN modality combination and the model using the demo + ANV modality combination (p-value = 0.520).
