CD25⁺Foxp3⁺ Treg in the CD4⁺ T cell compartment. Box and whiskers plot of percentage of CD25⁺Foxp3⁺ Treg in the CD4⁺ T cells (A). The medians are indicated by a line inside each box, the 25th and 75th percentiles are indicated by the box limits, and the lower and upper error bars represent the 10th and 90th percentiles, respectively. Correlation between CD25⁺Foxp3⁺ Treg cells and vitamin D levels in asthmatic patients using Pearson’s correlation coefficient (B).

Note: Mann–Whitney rank sum test assessed the differences between controls and patients.
