CD4 and tuberculosis: By contrast, HIV‐positive patients who did not receive ART within 6 months before DR‐TB treatment did not have a significantly higher mortality hazard than HIV‐negative patients (aHR = 1.09; 95% CI: 0.72–1.65), although those on ART had lower median CD4 counts than those not on ART (157 vs. 281 cells/μL, respectively; p = 0.02).
