  • ANC=antenatal care coverage level.

  • * International dollars are a hypothetical unit of currency that has the same purchasing power that the US$ has in the United States at a given point in time. Details of this approach are discussed elsewhere.12

  • † Intervention benefits are not comparable with current epidemiological estimates because results in this analysis are computed in relation to a “no intervention” comparator, which subtracts current levels of condom use, treatment of sexually transmitted infections, and antiretroviral treatment.
