Figure 1

Distribution of CD8⁺ T cell activation markers among HIV uninfected healthy controls, HIV infected Elite Controllers (EC) and HIV infected progressors. Shown is a scatter plot of the percent of CD38⁺DR⁺CD8⁺ T cells in healthy controls (HIN-neg), HIV-infected EC (EC) and progressors (PROG). The line through each scatter plot indicates the median value for the group. The significance of between-group activation marker levels was assessed by comparing EC with healthy controls and with HIV infected progressors using a Kruskal-Wallis test with Dunn's multiple post-test comparisons. P-values shown correspond to comparisons performed between the 2 groups linked by the line under the p-values.
