CD4 and tuberculosis: The final adjusted regression analysis showed three major risk factors that remained significant for developing TB: being less than 15 years old (adjusted hazard ratio (aHR) 7.88; 95% CI: 4.30–14.39, p value = 0.001), low CD4 count (aHR 23.3; 95% CI: 10.26–52.73, p value < 0.001) and ART interruption/no-ART (aHR 7.00; 95% CI: 4.26–11.49 and aHR 7.60; 95% CI: 4.48–12.88, p value < 0.001, respectively).
