CD4 and tuberculosis: After we adjusted for age, sex, ART use, previous TB treatment, adverse drug reactions, and a baseline CD4 cell count ≤200/mm3 by using the Cox proportional hazards model, we found that ART use was not associated with culture conversion after 2 months of treatment (HR 0.90, 95% CI 0.23–3.51) or culture conversion during treatment (HR 1.13, 95% CI 0.47–2.7).
