Kaplan-Meier plots.

<p>The observation period (days) is from 18 months (+/−6 months) after initiation of cART till death or 01/01/2010. The dotted line depicts the highest 50^th percentile and the full line depicts the lowest 50^th percentile. Analysis of survival linked to T cell subset are made with proportions of CD4+ and CD8+ cells respectively. Analysis using concentrations instead of proportions yielded similar results. Subsets were defined as naïve CD4/8(CD45RA+, CD62+), memory CD4/8 (CD45RA-, CD45R0+) and activated CD4 (HLA-DR+), and activated CD8 (HLA-DR+, CD38+).
