  1. Table reports respective statistics of significant clusters of the group comparisons between transgender and cisgender individuals. Clusters resulted from group comparisons corrected for total intracranial volume, age, and sexual orientation.
  2. For reasons of brevity no results below a threshold of k = 22 voxel have been reported.
  3. TW transgender women, Cg cisgender, pre before hormone treatment, post after hormone treatment, L left, R right, k cluster size, dF degrees of freedom, TFCE  threshold-free-cluster-enhancement with subsequent family-wise-error-correction. Coordinates are reported according to MNI-space.
