Figure 4. Forest plot of cumulative incidence of incident HIV infection during pregnancy and postpartum, by testing algorithm.

Figure 4

The retested cumulative incidence category is calculated as the number of new infections per number at risk for studies, and the assay cumulative incidence category is calculated based on cross-sectional testing of HIV-positive samples using assay algorithms designed to detect incident infections; cumulative incidence expressed as percent for both retested and assay categories. NAAT, nucleic acid amplification test; STARHS*, STARHS using BED capture enzyme immunoassay; STARHS**, STARHS using bioMerieux Vironosticka less sensitive enzyme immunoassay.
