Fig. 2From: Evaluation of multi-assay algorithms for cross-sectional HIV incidence estimation in settings with universal antiretroviral treatmentObserved longitudinal Incidence and cross-sectional Incidence estimates, HPTN 071 (PopART). The figure shows the observed longitudinal HIV incidence in the Validation Cohort, compared with incidence estimated using the LAg + VL MAA, the LAg + BR MAA, and the LAg + PepPairA MAA. Error bars represent 95% confidence intervals. MAA multi-assay algorithm, PY person yearsBack to article page
