Changes in the epithelial alarmin levels in the EBC of patients with IPF before and after 12 months of antifibrotic therapy according to the functional decline (stables—FVC % of predicted decline/year ≤ 5%; progressors—FVC % of predicted decline/year > 5%). Notes: Panels showing: (A) change in IL-25 EBC levels in stable IPF patients; (B) change in IL-25 EBC levels in progressor IPF patients; (C) change in IL-33 EBC levels in stable IPF patients; (D) change in IL-33 EBC levels in progressor IPF patients; (E) change in TSLP EBC levels in stable IPF patients; (F) change in TSLP EBC levels in progressor IPF patients; * p < 0.05, *** p < 0.001. Abbreviations: EBC—exhaled breath condensate, IPF—idiopathic pulmonary fibrosis, IL-25—interleukin 25, IL-33—interleukin 33, TSLP—thymic stromal lymphopoietin.
