Table 4.

Results of between-group analyses of cortical volume in regions of functional connectivity difference and the posterior cingulate cortex (seed region of interest). Results are corrected for intracranial volume (ICV) and presented as tenths of a percent (0.1% of ICV). There were no significance differences between groups.
