Correlation between proviral load in CD8⁺ cells and the proportion of CD8⁺ cells in PBMCs. The proviral load (PVL, copies per 100 cells) in CD8⁺ cells was strongly correlated with the proportion of CD8⁺ cells in PBMCs. The proportion of CD8⁺ cells in PBMCs is plotted against the proviral load in CD8⁺ cells (left panel; p = 0.02, Spearman’s rank correlation) and CD4⁺ cells (right panel; p = 0.06, Spearman’s rank correlation). The linear regression line was calculated excluding the CD4⁺ lymphopenic subject TBW (see text)
