Migrant status and sex interaction on ACC GM volume. (A) T-map of interaction effects between migrant status and sex on GM volume. A significant interaction effect is seen in the pACC (T = 4.17, P = .004, FWE-corrected within ROI). A significant decrease in pACC GM volume in migrant males compared with females and nonmigrants is observed. (B) Mean GM volumes of the most significant voxel (MNI: x = −6, y = 52, z = 7). Error bars indicate standard error of the mean. Coordinates refer to the MNI standard space. T-maps are displayed at P < .005 uncorrected for presentation purposes. The color bar represents T-values. GM, gray matter; pACC, perigenual anterior cingulate cortex; MNI, Montreal Neurological Institute; FWE, family-wise error correction for multiple comparisons; ROI, region of interest.
