PFC rGBC results for the clinical between-group analyses with region coordinates and relevant pairwise statistics reported. For completeness, we present all region comparisons. Effect sizes show standard Cohen's d estimates. Cohen's d was obtained by extracting the average Fisher's r-to-Z connectivity value for each subject across the entire identified cluster. This was done in order to characterize the magnitude of between-group effects across voxels surviving the type I error correction and provide a guide regarding sample sizes needed for future replications (Button et al., 2013).
