Branched EvoST
The highest performing model for this target used the whole ROI set and contained two first-order features: uniformity and mean. The LR coefficient signs indicate that the Branched EvoST is associated with higher image heterogeneity (i.e., lower uniformity values) and higher mean HU values. The first-order feature group was selected in 49% of CV splits, indicating this finding is relatively stable, but more data are needed to discover if this result is generalisable.
