CA = childhood abuse group; FA = fractional anisotropy; HC = healthy controls; ILF = inferior longitudinal fasciculus; IFoF = inferior fronto-occipital fasciculus; MD = mean diffusivity; PC = psychiatric control group; RD = radial diffusivity; SD = standard deviation.
↵* Indicates values that survive Bonferroni correction for multiple comparisons.
