CD4 and tuberculosis: Compared to patients who were down-referred to PHCs, adult patients who remained at the district hospital’s HIV clinic to complete TB treatment had a significantly lower median CD4 count (106.0 versus 136.0, p = 0.03) and were more likely to have microbiologically confirmed tuberculosis with AFB, culture or GeneXpert MTB/RIF (15.1% versus 7.9%, p = 0.002).
