(A) ROC curve showing the discriminative ability of GPNMB levels between the PD-CI and PD-NC patients. The AUC value was 0.775. (B) ROC curve showing the discriminative ability of the GMV/ICV ratio between the PD-CI and PD-NC patients. The AUC value was 0.671. (C) ROC curve showing the discriminative ability of the combined GPNMB levels and the GMV/ICV ratio between the PD-CI group and the PD-NC group. The AUC value was 0.803.
