From: Interleukin-31 expression and relation to disease severity in human asthma
Serum IL-31 levels in relation to asthma control.
Patients were classified into three groups based on ACT scores. Patients with uncontrolled asthma (n = 15) had statistically higher serum IL-31 levels than patients with partly controlled (n = 18) and completely controlled asthma (n = 11) (A). The correlation between serum IL-31 levels and ACT score was assessed using Spearman’s rank correlation analysis (B). Data are presented as median with interquartile range. **p < 0.01, ***p < 0.001.
