Model 1: After adjusting sex, age, occupation, marital status, route of HIV infection, duration of ART, initial ART regimens, ART regimens at survey, and missed doses, patients with VL 50–999 copies/mL and DR (AOR 3.8, 95% CI 2.6–5.5, p < 0.01), VF and no DR (3.1, 2.4–4.1, p < 0.01), VF and DR (5.8, 4.5–7.4, p < 0.01) had higher detection rates of CD4 cell counts < 200 cells/μL, compared with VL 50–999 copies/mL and no DR. Here, CD4 is linked to HIV infectious disease.
