Abstract
[...] analysis three consisted of a moderator analysis where a cluster analysis of all studies was broken down first by a meta-analysis of volumetric differences ofbrain structures, which was followed by tests of group differences to determine potential moderators and meta-analysis of those clusters that were homogenous for a variable. [...] they identified a need for further comparisons of those with a PTSD diagnosis, to those with trauma exposure and those without trauma exposure to parse out effects on structure and whether brain structure abnormalities are premorbid.
