Mediation results from model 1 with DHEA as the mediator. Higher trauma‐related anxiety symptoms (x) related to lower levels of salivary DHEA (mediator), which in turn related to smaller anterior pituitary volume (y). There was no direct association between anxiety symptoms and anterior PG volume. Standardized estimates are shown in the figure, with significant paths indicated with bold black lines (p < .05) and nonsignificant paths indicated with black dotted lines.
