Note. Table 3 summarizes regions where lesion volume was significantly associated with language performance in the comprehension domain. The results are presented at a threshold of , based on cluster size and the permutation method. In addition, the permutation-corrected values were corrected for the total number of language measures examined () using the Benjamini-Hochberg procedure. Significant peak regions are reported with the corresponding coordinates, T and values, degrees of freedom, and effect sizes, as well as AAL regions included in the significant cluster; LH: left hemisphere; IFG: inferior frontal gyrus; STG: superior temporal gyrus; MTG: middle temporal gyrus.
