Fig. 3From: IL-1β augments TGF-β inducing epithelial-mesenchymal transition of epithelial cells and associates with poor pulmonary function improvement in neutrophilic asthmaticsa–c The correlations of baseline IL-1β mRNA expression with spirometry change in all asthmatic patients. d–f The correlations of baseline IL-1β protein level in sputum supernatant with spirometry change in all asthmatic patients. g–i The correlations of baseline IL-1β mRNA expression with spirometry change in neutrophilic asthmatic patients. j–l The correlations of baseline IL-1β protein level in sputum supernatant with spirometry change in neutrophilic asthmatic patients. The data are presented as dot plots, with fitted regression lines. mRNA and protein expression were log transformed, Spearman R-values and p-values are indicatedBack to article page
