CD4 and tuberculosis: In a multivariate model adjusted for age, gender, body weight, CD4 cell count, the presence of tuberculosis and antiretroviral regimen, risk factors for poor survival were lower CD4 cell counts at starting cART (HR 1.77, 95% CI 1.157-2.72, p = 0.009 for CD4 cell count <50 compared with >100 cells/μl) (Table 2 and Figure 1).
