Average age of all participants in sample (PTSD and comparison groups). None of the comparison participants listed above had a PTSD diagnosis at the time of the study

Despite overlapping samples present in overall database, none of the studies included in the individual ROI meta-analyses reported here contained overlapping samples

Automated method used was FreeSurfer image analysis suite.
