Notes: Adjusted for age, gender, income, wealth, and race-ethnicity. CI = confidence interval; OR = odds ratio.

^aCI includes 1.00 due to rounding.

^bTest of the null hypothesis that all beta coefficients (except the intercept) are equal to 0. Reported value is an average of the values obtained from each imputed data set.
