Evolution of CD4⁺ and CD8⁺ T cells and their memory and activated subsets throughout HAART. Absolute numbers of CD4⁺ T and CD8⁺ cells and their subsets of memory (CD45RA⁻CD45RO⁺) and activated (CD69⁺ or HLA-DR⁺) cells are represented on the left graphs, and percentages, on the right graphs. Gating strategy used to define these populations are depicted in Additional file 1: Figure S1. All comparisons were performed using One Sample t-Test, except the ones marked with ^A, in which One-Sample Wilcoxon Signed Rank Test was used. * represents 0.05 > p > 0.01 and **, p ≤ 0.01
