This figure displays the relationship between DHEA levels, insular-hippocampal structural covariance, and working memory.
The beta coefficients and standard errors, extracted from previous analyses corrected for multiple comparisons using random field theory (see Methods, sections 2.5.1 and 2.5.2 for more details), are displayed in the center of the figure:
(1) On the left, for the relationships between DHEA and insular-hippocampal covariance;
(2) On the right, for the relationship between insular-hippocampal covariance and working memory.
In addition, test statistics and p-values for the formal Sobel-Goodman mediation tests are displayed at the bottom of the figure.
