Edge-wise analysis (alpha 2). Subnetworks of functional connections showing a significant difference between the three groups at alpha 2. At each part, the top row presents graph-based representations of these subnetworks, with each region represented as a red sphere plotted according to the stereotactic coordinates of its centroid, and each suprathreshold edge represented as a dark green line. The size of the node represents the number of significantly different connections from the node itself. For all edges, connectivity was higher in G1 > G2 (A), G1 > G3 (B) and G2 > G3 (C). Bottom row presents the proportion (%) of each type of connection in each subnetwork, as categorized according to the lobes each edge interconnects. F: Frontal, T: Temporal, P: Parietal, C: Central, and O: Occipital.
