Correlation was assessed in 46 patients in whom total HIV-1 DNA was detected both in the blood and rectal biopsies, representing patients from three cohorts: SRCV on antiretroviral therapy (ART), Chronic ART, and long-term non-progressors (LTNP). Data is shown as log10 copies/million (c/M) cells in rectal biopsies and log10 c/M peripheral blood mononuclear cells (PBMCs) in blood. Correlation of blood HIV-1 usRNA and total HIV-1 DNA (B), HIV-1 usRNA and integrated HIV-1 DNA (C), integrated HIV-1 DNA and total HIV-1 DNA (D) and CD4/CD8 ratio and integrated HIV-1 DNA (E). Data is shown as log10 c/M PBMCs in detectable patients from three cohorts: SRCV on ART, Chronic ART, and LTNP (B–E). To assess correlations between the markers, a linear regression was performed.
