Correlation between the decline rate of phenotypic markers in IFN-γ⁺CD4⁺ cell in peripheral blood stimulated with ESAT 6/CFP-10 and that of chest CT severity score from before TB treatment to two or six months after TB treatment. Correlation of the decline rate between CD27⁻ and chest CT severity score (A), CD38⁺ and chest CT severity score (B), and CD27⁻CD38⁺ and chest CT severity score (C) from 0 to 2 m were analyzed; Correlation of the decline rate between CD27⁻ and chest CT severity score (D), CD38⁺ and chest CT severity score (E), and CD27⁻CD38⁺ and chest CT severity score (F) from 0 to 6 m were analyzed. Statistical analyses were performed using the spearman test. r and P-values are indicated. 0 m Before the TB treatment initiation, 2 m 2 months after TB treatment initiation
