Note 95% CI indicates lower/upper limits of the confidence interval. Intercept corresponds to the mean for male controls at average age who never completed a four-year degree and household earns < $90,000.

^aindicates p < 0.05,

^bindicates p < 0.01,

*** indicates p < 0.001. P-values are two-tailed.
