a Boxplots of forced vital capacity (FVC) % predicted and b diffusion capacity of the lungs for carbon monoxide (DLCO) % predicted, measured in hospital at start of the study, start of treatment with pirfenidone, 12 and 24 weeks after start of treatment. In total, n = 8 patients were included in the analysis of in-hospital measurements. At t = 0 and t = 24 weeks, pulmonary function data from n = 7 patients were available for analysis
