Table 5.

The p values indicating whether the addition of a particular feature significantly improved classification ability over using the MRD alone when individual ROI pairs were used in the training of each model (MInd). During validation, averages of changes in feature values were used.

Feature A1 IBEX Pyradiomics
Mean p<0.002 p<0.002 p<0.002
Min 0.024 p<0.002 0.024
Median p<0.002 p<0.002 p<0.002
Entropy p<0.002 p<0.002 p<0.002
GLCM sum average p<0.002 p<0.002 p<0.002
GLCM sum entropy p<0.002 p<0.002 p<0.002
GLCM difference entropy p<0.002 p<0.002 p<0.002
GLCM entropy p<0.002 p<0.002 p<0.002

Note: Bolded p-values indicate features that were considered significantly correlated with RP for MInd models but not for MAvg models.
