CD4⁺ T cell subsets in the peripheral blood (PB) and the lymph node (LN) and the correlation between PB and LN. The frequencies and correlations of (a) CD4⁺ T cells within CD3⁺ T cells, (b) CD4⁺ naive T cells within CD4⁺ T cells, (c) CD4⁺ central memory (CM) T cells within CD4⁺ T cells, (d) CD4⁺ effector memory (EM) T cells within CD4⁺ T cells and (e) CD4⁺ effector memory CD45RA⁺ (EMRA) T cells within CD4⁺ T cells are represented. Frequencies of cells are depicted as individual percentages as well as median and interquartile range (left plots). A Spearman's rho was shown only when a significant correlation was present; n = 38 for peripheral blood and n = 38/37 for lymph node samples. Significant differences were calculated and shown (*P < 0·05; **P ≤ 0·01; ***P ≤ 0·001).
