Note: Significance of the between-group difference, p-value, for Age, IQ, Income and Education is based on the one-way ANOVA; significance of the between -group difference, p-value, for Male is based on the Pearson’s chi-squared test (χ2). Age is significantly different across patients groups; F(2,54) = 12.59, p < 0.001. Income is assessed on a 10 point scale (SM S.1.), where “3” = $25,000–34,999; “4” = $35,000–49,999”, and “5” = $50,000–74,999. Education is assessed on a 5-point scale (SM S.1) with “4” = College Graduate, and “5” = Advanced graduate or professional degree.
