However, pooling the XpYp data from labeled volunteers revealed that telomere lengths were maintained to a slightly greater extent in the CD57 − memory CD4 + T cell population compared with the CD57 + memory CD4 + T cell population ( Figure 3 D), and pooling the 17p data from volunteers in cohort 3 yielded a similar result with borderline significance (p = 0.037, Mann-Whitney U test; data not shown).
