Immunohistochemical staining of EPCR in the normal (A), non-PE (B), PE (C) and ARDS (D) lungs. The EPCR expression in small blood vessels are shown in the inset of each micrograph. The H-score expression is demonstrated by bar graphs for PE (E) or ARDS (F) lungs, to compare those expression Friedman test was performed (**; p-value < 0.001, ***; p-value <0.0001). Negative correlation between the level of EPCR and some histopathological changes was observed using Spearman test (G-I).
