With the exception of HIV type (p = 0.648) and TB/HIV coinfection status (p = 0.641), patients on ART were significantly different from those who were not ART in terms of age (p<0.001), sex (p = 0.002), educational attainment (p<0.001), marital status (p<0.001), CD4 count at baseline (p<0.001) and clinical stage of the disease (p<0.001) (Table 2). This evidence concerns the gene CD4 and tuberculosis.
