Fig. 2From: IL-1β augments TGF-β inducing epithelial-mesenchymal transition of epithelial cells and associates with poor pulmonary function improvement in neutrophilic asthmaticsThe improvement of lung function a–c and ACT scores d after six months standardized therapy among four subgroups of asthmatic patients. ΔFEV1(V2-V1): absolute change in FEV1, calculated by the difference between FEV1 after six months treatment and baseline FEV1; ΔFEV1%(V2-V1): absolute change in percentage of the predicted FEV1, calculated by the difference between percentage of the predicted FEV1 after six months treatment and baseline percentage of the predicted FEV1; ΔFEV1(V2-V1)/FEV1(V1): FEV1 change ratio, calculated by absolute change in FEV1 divided by baseline FEV1. ΔACT(V2-V1), absolute change in ACT, calculated by the difference between ACT after six months treatment and baseline ACTBack to article page
