The frequency of CD25^brightCD4⁺ T cells of patients with rheumatoid arthritis is not associated with clinical parameters. Peripheral blood (PB, left column) and synovial fluid (SF, right column) were analyzed for the correlation with (a) disease duration, (b) the presence or absence of rheumatoid factor (RF), (c) the presence or absence of erosions, (d) the level of C-reactive protein and (e) intra-articular cortisone treatment. In (a), (b) and (c) each symbol represents one patient; that is, mean values of CD25^brightCD4⁺ T cells from the different visits. In (d) and (e) each symbol represents a single visit; the number of symbols in each diagram is presented in brackets.
