Association between epithelial markers and clinical severity during hospitalization. Surfactant protein (SP) A levels according to a the severity scale, b acute distress respiratory syndrome (ARDS), c the development of organizing pneumonia and d pulmonary embolism. Kruskal–Wallis test or Mann–Whitney test are applied, as appropriate. The adjusted P-values are obtained by Dunn’s test correction
