CD4 and tuberculosis: Furthermore, when the above 50 HIV-positive patients coinfected with MDR TB were categorized into two groups composed of Group 1: 28 (56%) patients with CD4+ T-cell counts <200 cells/mm3 and Group 2: 22 (44%) patients with CD4+ T-cell counts ≥200 cells/mm3, patients with CD4+ T-cell counts <200 cells/mm3 converted faster (5.379 ± 0.456 weeks; 95% CI: 4.486–6.273) than those with CD4+ T-cell counts ≥200 cells/mm3 (8.000 ± 0.746 weeks; 95% CI: 6.538–9.462), and this difference reached statistical significance using the Wilcoxon rank sum test (p = 0.004) as depicted in Figure 1 below.
