Correlations were found at baseline between (A) age with thymic volume (thymic tissue score is also shown); (B) age with TREC/106PBMCs; (C) thymic volume and TREC/106 PBMCs; and (D) absolute counts per microliter of naı̈ve T cells (CD4+ plus CD8+) and TRECs. The Spearman correlation coefficient and P values are indicated within each figure.
