Evaluation of cutoff values for plasma IFN-γ concentration using the differences of increase in the CD4⁺ cell count from the start of ART (baseline). (a) Cutoff values for plasma IFN-γ concentration were increased by 0.1 from 0.5 to 10. The participants were divided into two group and group comparisons were performed. P values of the Mann-Whitney U test are indicated. The range of cutoff values with the smallest P value are shown in the top of figures. (b) The differences of increase in CD4⁺ cell count between two groups. The range of cutoff values with the maximum differences is shown in the top of figures
