Relations between baseline TREC counts and response to HAART in thymic function–related variables.

Fifteen HIV-1–infected patients receiving HAART were split into 2 groups of below (group 1) or equal or above (group 2) the median TREC counts at baseline and analyzed for changes in TREC/μL (A), thymic volume (B), and CD4⁺ plus CD8⁺ naı̈ve T-cell counts (C). Only the group 1 patients had significant increases versus baseline in these markers (*P < .05, Wilcoxon signed rank test). The number of patients in group 1 and group 2 at each time point is shown at the bottom of each panel.
