Note:—Pct. Diff. indicates percentage difference; FDR, false discovery rate.

Ipsilateral and contralateral columns represent mean (standard deviation) cortical thickness measures in millimeters.

a

Paired t tests comparing the ipsilateral and contralateral regions were used to calculate P values. The Benjamini-Hochberg procedure was used to control the false discovery rate.

b

Corrected P values < .05.
