Recovery of naive CD4⁺ T cells.

Sequential assessments of median CD45RA⁺CD4⁺CD3⁺ T-cell counts (at months 3, 6, 9, 12, 15, 18, and 24) are shown for both unselected () and CD34⁺ selected (■) groups. P values for median comparisons between groups are given at each time of follow-up. Fractions of CD62L⁺ T cells are represented in □.
