P-values derived from the Kruskal-Wallis test and the post-hoc Connover-Iman test for each of the most significant characteristics chosen for each regressor. Features are ranked from highest importance in the HC group to lower, left-right. a A total of 16 unique features were selected for the combined regressor, from which 3 demonstrated significant differences in the pairwise comparisons. b A total of 17 unique features were chosen for the regressor trained on the Morphological Feature Set. Up to 10 features demonstrated significant differences in importance between groups. c shows the 17 most significant characteristics for the regressor trained on the Intensity Feature Set. No significant differences were found during the Kruskal-Wallis test
