Fig. 2: Mean scores and heritability estimates for the EQ.

Mean scores and standard deviations for scores on the EQ (a). The effect size of the difference between males and females for the EQ scores was Cohen’s d = 0.65. The bar on top and the number represents the statistical significance of the male–female difference in mean scores for the EQ. Mean estimates and standard errors for heritability for scores on the EQ (b) for the females-only GWAS, males-only GWAS, and the non-stratified GWAS. Numbers on top of the graphs represent P-values for each heritability estimate. Note that the y-axis does not start at 0
