Fig. 2: Classification performance of group differentiation.

The 30 anatomically derived morphometric areas from the ICA networks thresholded at z = 3.5 and overlaid on the ROC curves for each group differentiation using harmonised grey matter values. Model training results are presented in solid lines, model evaluation in dotted lines. Black ROC: Con-Psy vs. Con-PD, red ROC: Con-Psy vs. FEP, blue ROC: Con-PD vs PDP; purple ROC: Con-PD vs. PDN.
