FA, fractional anisotropy; LH, left hemisphere; RH, right hemisphere; CAPS, Clinician Administered PTSD Scale for DSM-IV; r, partial correlation controlling for age; sex, head motion, and antidepressant use; fmajor, corpus callosum forceps major; fminor, corpus callosum forceps minor; ATR, anterior thalamic radiations; CST, corticospinal tract; ILF, inferior longitudinal fasciculus; SLFP, superior longitudinal fasciculus parietal endings; SLFT, superior longitudinal fasciculus temporal endings. Bonferroni method was used to adjust alpha threshold for multiple comparison (0.05/12 = 0.004). No results were significant, before or after correction.
