Demographic and cognitive scores across genotypes. Values in parentheses denote SDs, except for those in n column, which denote the number of female participants. p-values correspond to the null hypotheses that these values are equivalent across all three groups. For n, the p-value is derived from a χ2 test on the number of females and males across genotype groups. For all other variables, p-values are derived from three-way ANOVAs.
