Table 2. Significant between-group differences in FA/MD values in trauma-exposed victims with and without PTSD (P < 0.05, AlphaSim corrected).

Diffusion parameter	Region of white matter	Peak MNI coordinate			Number of cluster voxels	Peak T value
		x	y	z
FA	R-middle temporal gyrus WM	50	10	-32	126	-5.46
	R-anterior cingulate cortex WM	14	30	26	117	-5.38
	R-midbrain WM	12	-24	-10	121	-3.86
	L- gyrus rectus/medial OFC WM	-16	18	-16	158	-4.75
MD	R-superior frontal gyrus WM	22	38	32	189	-4.52
	L-subcallosal gyrus WM	-18	12	-12	171	3.65

R = right; L = left; PTSD = posttraumatic stress disorder; FA = fractional anisotropy; MD = mean diffusivity.

T < 0 indicates decreased FA/MD values in trauma-exposed victims with PTSD.

T > 0 indicates increased MD values in trauma-exposed victims with PTSD.
