Correlation between gating strategies of regulatory T cell (Treg) and CD4⁺CD25^{h i}. The three Treg definitions are CD4⁺CD25^hiCD127^low,CD4⁺CD25^hiCD127^lowFoxp3⁺, and CD4⁺CD25^hiFoxP3⁺. The overall correlation was positive moderate-strong between the Treg definitions, with the similarity between the intracellular panels being especially remarkable. The values inside the boxes indicate the Spearman correlation strength. Low association was between 0.1-0.3; moderate positive association was between 0.3-0.5; and strong positive association was 0.5-1. (*) p value ≤ 0.05; (**) p value ≤ 0.01.
