CD4 and tuberculosis: Persons who received > 7 months of anti-tuberculosis treatment had a lower risk of death than persons who received 5-7 months of treatment after controlling for CD4+ lymphocyte count and HIV-1 RNA at the time of tuberculosis diagnosis, as well as timing of ART initiation in relation to anti-tuberculosis therapy initiation, but the difference was not statistically significant (aHR = 0.58; 95% CI 0.17, 1.94; P = 0.38).
