Fig. 4. Correlations between inflammatory cells in esophageal epithelia and eosinophilic esophagitis (EoE) endoscopic reference score (EREFS) of controls and patients with EoE. Correlations between eosinophils and EREFS (A), mast cells and EREFS (B), T cells (CD3+) and EREFS (C), and Tregs (FOXP3+) and EREFS (D) are shown (n = 34). The Spearman test is used for determining correlations between data sets. ****P < 0.0001. HPF, high power field.
