In CSF of individuals on sustained ART started in chronic infection, cell-free HIV RNA was detected in 4% (95% CI: 1%–12%), CA-HIV RNA was detected in 9% (95% CI: 3%–18%), and CA-HIV DNA was detected in 48% (95% CI: 36%–60%). The boxes indicate percentage positive (A). Detection of CA-HIV DNA in CSF cells did not significantly associate with pre-ART CD4 count (B), HIV RNA level (C), CD4/CD8 ratio (D), or years on ART (E), where the boxes indicate median values.
