Correlation between the Dll4 expression levels and the CD3 ⁺ , CD3 ⁺ CD4 ⁺ , CD3 ⁺ CD8 ⁺ , CD3 ⁻ CD19 ⁺ , or CD3 ⁻ CD16 +  CD56 ⁺ cell subsets in HFMD patients (n = 82). Dll4 mRNA expression and lymphocyte subsets were assessed by real-time q-PCR and FACScan analysis respectively, as described in the Methods. Each dot represents individual case and each line indicates the best-fit line. R² values were calculated by Spearman rank correlation coefficient test.
