  1. Linear mixed-effects models for relative (%) and absolute (L) change from baseline in FVC over 48 weeks for patients with IPF, with and without emphysema, in the clinical trial cohort (N = 455) using CPFE dichotomous at 15%
  2. CPFE combined pulmonary fibrosis and emphysema; FVC forced vital capacity; ILD interstitial lung disease; IPF idiopathic pulmonary fibrosis
