Fig. 2: Effects of PTSD diagnosis on cerebellar subregion volumes.

Atlas-based effect size (Cohen’s d) maps and MNI-based coronal slices (top: y = −72; bottom: y = −54) of the significant between-group differences for cerebellar subregion volumes in PTSD vs. Controls. Negative effect sizes reflect smaller volumes in PTSD. Regions significant at p-FDR < 0.05 are depicted in color, with the exception of right lobule V, where p-FDR = 0.051 after adjustment; right lobule V was significant p-FDR = 0.046) when examining PTSD severity instead of diagnosis. Grey-shaded subregions were non-significant. CM corpus medullary.
