Fig. 2From: Interaction between childhood trauma experience and TPH2 rs7305115 gene polymorphism in brain gray matter volumeSignificant mediation effect in the environment-brain structure-behavior pathway. A The GMV of the right PPTha was a significant mediator between CTQ score and STAI score. B The GMV of the right PPTha was a significant mediator between CTQ score and STAI score only in genotype of TPH2 rs7305115 G carriers compared with A homozygous. 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; PPTha: the Posterior Parietal thalamusBack to article page
