Expression of activation markers by Tregs and non-Tregs.

a: data are shown as median (range) percentage of Tregs (defined as CD3+CD4+FOXP3+) or non-Tregs (defined as CD3+CD4+FOXP3−) expressing each marker. Markers were measured at wk0 in 11 and 9 HIV-infected patients for CD69 and HLA-DR respectively, and in 8 controls for both markers.*and italics: indicates a significant difference between controls and HIV-infected subjects (p≤0.05);#: indicates a trend towards significance (p≤0.10).b: data are shown as relative changes in geometric means, expressed in % (coefficient of variation). Formulas used to calculate these values are as follows: relative change in geometric means = 100*[geometric mean (post HAART/wk0)]-100; coefficient of variation = [exp(standard deviation on log scale)-1]*100. Differences versus baseline were analyzed using the repeated measures analysis of variance.oand italics: indicates a significant difference versus wk0 (p≤0.05);indicates a trend towards significance (p≤0.10).
