In post-hoc exploratory analyses, the increases in tuberculosis diagnoses in the intervention group versus the standard-of-care group were not confined to high-risk subgroups, unlike mortality, with an adjusted absolute risk increase of 7·0% (95% CI 4·1–10·0) in tuberculosis diagnoses in patients with CD4 counts of 100 cells per μL or more, and 8·0% (5·0–11·1) in those not clinically suspected of tuberculosis at admission (appendix). The gene discussed is CD4; the disease is tuberculosis.
