Table 1.
Coefficients (s.e.) predicting the log-odds of death at specific age intervals for males as a function of the annual cohort sex ratio at birth and control variables. Sex ratio scaled as a z-score (i.e. one unit change is 1 s.d.). All analyses control for clustering of sibling observations within mother.
| variable | death before 1 year |
death 1–4 years |
death 5–14 years |
death 15–49 years |
