ORadj (95% CI)a | |
|---|---|---|---|
| Study cohort | Comparison cohort | ||
| All birth defects | 45/783b (5.7) | 227/3,343b (6.8) | 0.89 (0.6–1.2) |

a
ORadj, adjusted odds ratio; CI, confidence interval.
b
Various denominators are due to various numbers of elective terminations of pregnancy/spontaneous abortions with major, minor, or genetic birth defects considered in numerators and denominators.
