Notes: Results from separate linear regression models for reproductive timing for each polygenic score and reproductive event separately for unrelated white females and sister fixed-effects. Standard errors are shown in parentheses. All models include appropriate sample weights and correct for clustered sampling design. OLS = ordinary least squares; FE = fixed effects.
