Association between epithelial and endothelial markers and the grades of DLCO alteration. a Levels of surfactant proteins (SP) A, SP-D and secretory leukocyte protease inhibitor (SLPI) as epithelial markers and b intercellular adhesion molecule 1 (sICAM-1) and Angiopoietin-2 as endothelial markers significantly increased in patients with the most abnormal DLCO (≤ 50%). Kruskal–Wallis tests are applied, and the adjusted P-values are obtained by Dunn’s test correction
