* Viral load (VL) was unknown for 16 participants at the first data merger. ** LOD: Lower limit of detection. LOD was >200 copies/mL for the specific assay used for the participants’ latest measurement, with the results being a VL < than the specific LOD. *** CD4 was unknown for 71 participants at the first data merger.
