Significant mediation effect in the environment-brain structure-behavior pathway. The GMV of the right PhG_A28/34 was a significant mediator between CTQ score and STAI score. The direct and total effects were labeled with path coefficients and p values. The significant indirect effect was labeled with path coefficients and 95% confidence intervals. CTQ: Childhood Trauma Questionnaire; STAI: Spielberger’s State-Trait Anxiety Inventory; GMV: gray matter volume; PhG_A28/34: the Parahippocampal Gyrus area 28/34
