These analyses were intended primarily for descriptive purposes. However, we recognize the need to control for multiple comparisons in order to reduce the risk of making Type I errors. Therefore, we created 3 families including 2 correlations each (one for each of the significant regions) and performed a Bonferroni correction, making the critical alpha level for significance 0.025. This has been clarified in the statistical analysis section.
I am uncertain why the authors only report the effect sizes of group differences in the first run.
