Fig. 3. Correlation between CD69 and Th-cell levels. Levels of (A) Th1, (B) Th2, (C) Th17, (D) Th22, and (E) Tfh cells in function of CD3+, CD4+, and CD8+ T cells in the CD69^high and CD69^low groups, and correlations between these Th cells and CD69 levels on CD3+, CD4+ and CD8+ T cells. None of the continuous variables conformed to the normal distribution. Differences were analyzed using the Mann–Whitney U test. Spearman correlation was used for correlation analysis. *P<0.05, **P<0.01, ***P<0.001, ****P<0.0001.
Abbreviations: Th, T-helper; Tfh, T follicular helper.
