Hippocampus: Gender does not moderate hippocampal volume deficits in Adults with Posttraumatic Stress Disorder: A Meta-Analysis

This article explores if gender moderates hippocampal volume deficits in people with PTSD. The researchers identified 23 studies that met the criteria and calculated effect sizes for differences in hippocampal mean volumes. They used the percentage of men with PTSD as the continuous moderating variable. The researchers were trying to prove if gender effects this because studies have shown a higher point prevalence of PTSD in women compared to men. They found that the hippocampal volume was smaller in the PTSD group compared to the control group. However, gender did not significantly change any effect sizes in the metagression or subgroup. They concluded that hippocampal volume deficits in PTSD are independent of gender.
