a

Number of patients analyzed at the laboratory. In almost all cases, two replicates per subject were analyzed for each phenotype at each laboratory; occasionally, only one replicate per patient was analyzed.

b

Laboratory C did not measure CD26+ CD4+, CD26+ CD8+, CD25+ CD8+, CD25+ CD4+, DR+ CD4+, and CD38+ CD4+ cells.
