Fig. 4From: Blood Krebs von den Lungen-6 levels predict treatment response to antifibrotic therapy in patients with idiopathic pulmonary fibrosisCorrelation between relative FVC and KL-6 level changes in patients with high baseline KL-6 level. Correlation between relative changes in FVC (over 6 months) and a absolute and b relative change in KL-6 levels (over 1 month) in patients with high baseline KL-6 levels (≥ 500 U/mL).
