Frequencies and absolute counts of activated CD8 T cell subsets. A) Frequencies of activated CD8 T cell subsets according to CD38 and HLADR expression during follow up. The numbers in each quadrant correspond to the mean of all patients’ percentage of the subpopulation among all CD8 T cells. B) Mean ± 1 SEM absolute counts of CD38+ HLADR- CD8 T cells. C) Mean ± 1 SEM absolute counts of CD38+ HLADR+ CD8 T cells. D) Mean ± 1 SEM absolute counts of CD38- HLADR+ CD8+ T cells. * Significant difference between the TB IRIS and No IRIS groups. # Significant difference between the TB IRIS and Other IRIS groups. Two-group differences were determined only when the Kruskal-Wallis test showed overall group effects.
