CD4 and tuberculosis: Patients on cART shared the same risk factors of TB with the patients who never started cART, namely: originating from Sub-Saharan Africa (HR 5.15; 95% CI 2.76-9.60; P < 0.001), CD4+ cell count ≤ 200 cells/μl (HR, 1.90; 95% CI 1.14-3.15; P = 0.013) and viral load ≥ 5 log10 copies/ml (HR 1.77; 95% CI 1.11-2.82; P = 0.016).
