↵a Statistical significance after Bonferroni correction (P < .0038, considering 13 independent tests). Upward arrows indicate increased MRI measures compared with controls, and downward arrows indicate decreased MRI measures compared with controls. ↑ represents P < .05, ↑↑ represents P < .01, ↑↑↑ represents P < .001, and ↑↑↑↑ represents P <0 .0001.
