CD4 and tuberculosis: In the multivariate model which included sex, age, country, CD4+ cell count, viral load, ART assignment and the interaction term for sex and ART assignment, using the group with no disease as reference, an ongoing diagnosis of TB at randomization was associated with an increased risk of death (AHR 3.41; 95%CI: 1.72–6.75) and this association was highly significant (p<0.001).
