The frequency of phenotypic markers of CD27⁻ and CD27⁺ (A), CD38- and CD38⁺ (B), CD27⁻CD38⁻ and CD27⁺CD38⁺ (C) and CD27⁻CD38⁺ and CD27⁺CD38⁻ (D) on IFN-γ⁺CD4⁺ T cells in peripheral blood stimulated with ESAT-6/CFP-10 before and after 2 months of TB treatment. E The frequency of IFN-γ⁺CD4⁺ on CD4⁺ T cells in peripheral blood stimulated with ESAT-6/CFP-10 at baseline, 2 months and 6 months after TB treatment. Statistical analyses for paired data were performed using the Wilcoxon-signed rank paired test. Median values, interquartile range and P-values are indicated. 0 m Before the TB treatment initiation, 2 m 2 months after TB treatment initiation
