---|---|---|---|
Pregnancies (per 100 person-years) in HIV-infected women |
7.40 | 1.40-18.10* | 38, 43 |
Pregnancy outcomes among HIV-infected women | |||
Live births per pregnancy | 36.00% | 27.00-45.00% | 38 |
Probability of teratogenic events among HIV-infected women | |||
Prevalence of teratogenic events, no efavirenz exposure† |
2.72% | 95% CI: 2.68-2.76% | 39, 42 |
Prevalence of teratogenic events with efavirenz exposure |
2.90% | 95% CI: 1.60-4.90% | 39 |
The range for this sensitivity analysis was derived using age-stratified pregnancy rates.43
The confidence intervals reported around the general population rate of teratogenic events from the Metropolitan Atlanta Congenital Defects Program (MACDP) used for the prevalence of teratogenic events with no efavirenz exposure were calculated by the Antiretroviral Pregnancy Registry.39 MACDP does not publish confidence intervals because population-based surveillance does not involve sampling.
