Note. Model 1 includes age, race, ethnicity, and gender (for colorectal screening) as covariates. Model 2 further includes socioeconomic covariates (education, income, and wealth). These results were based on regression with all five traits entered simultaneously in one model, but results were mostly similar when separate regression were run for each trait (see Supplementary Material, Tables S8–S11).
