Conversely, higher CD4 count (51 to 100 cells/μL HR 0.57, 95% CI (0.38 to 0.86), p = 0.007; 101 to 200 cells/μL HR 0.42, 95% CI (0.30 to 0.58), p < 0.001; and > 200 cells/μL HR 0.11, 95% CI (0.08 to 0.15), p < 0.001) was associated with reduced hazard for TB compared to CD4 ≤ 50 cells/μL. This evidence concerns the gene CD4 and tuberculosis.
