CD4 and tuberculosis: Similarly, CD4+ count less than 200 cells/mm3 at ART initiation (aSHR = 9.95 vs CD4+ count > 350 cells/mm3, 95%CI 2.38–41.60, p = 0.002) and urban residence (aSHR = 4.60 vs non-urban residence, 95%CI 0.96–21.86, p = 0.05) were independently associated with higher risk of TB among participants on second-line ART (Table 3).
