Average forced vital capacity of patients with idiopathic pulmonary fibrosis.

Notes: The mean %FVC 1 year before nintedanib administration was 80.5% ± 14.2% and 61.9% ± 11.4% in Mild to Moderate Group and Severe Group, respectively. The %FVC at the start of nintedanib administration was 72.6% ± 15.5% and 46.4% ± 7.0%, respectively; and the %FVC after 1 year of nintedanib administration was 69.8% ± 19.0% and 43.2% ± 13.6%. In both groups, nintedanib significantly suppressed the deterioration of the FVC.
