Higher HIV viral load at baseline (HR, 1.01; 95% CI, 1.001–1.1; P value = .001) and having diagnosed AIDS (HR, 12.7; 95% CI, 4.9–32.9; P value <.001) were also significantly associated with the development of active TB among PHIV, whereas higher CD4 cell count at baseline was a significant protective factor against developing TB (HR, 0.12; 95% CI; .05–.28, P value <.001) (Table 2). Here, CD4 is linked to tuberculosis.
