Standardized regression coefficients and 95% confidence intervals are reported for continuous variables. Coefficients on the binary variables are shaded gray and report the standard deviation change in the outcome by moving from 0 to 1 on the binary variable. Cohort fixed effects are included for each model. Adjusted R-squared is presented for each model.
