Figure 2: Three-dimensional maps showing correlations between The Reading House total scores and gray matter cortical thickness for the total sample (2a; p-FWE<0.05), children from higher-SES households (2b; p-FWE<0.10) and children from lower-SES households (2c; p-FWE<0.10), controlling for age. Areas with significant positive association (thicker) are shown in red hues. For each, upper views are medial, lower views are lateral and central view is superior. Numbered cortical regions are detailed in Table 3.
