These proportions were higher among PLWH with a history of tuberculosis at baseline versus those without (4.8% vs 2.2%), a detectable (≥50 copies/ml) versus undetectable HIV viral load (4.7% vs 1.7%), and a baseline CD4 count <200 vs ≥200 cells/μl (3.5% vs 2.4%). The gene discussed is CD4; the disease is tuberculosis.
