CD4 and tuberculosis: The participant profile in the diagnostic trial differed notably from this study, with lower ART coverage and CD4 counts (median 84 cells per μL vs 227 cells per μL), and a greater proportion of participants had tuberculosis (intervention groups: 51·6% vs 21·8%), reflecting different inclusion criteria (clinical suspicion of tuberculosis compared with an unselected population in our STAMP trial), as well as underlying population trends in ART coverage.
