A significant statistical correlation was registered between ICAM-1 immunoexpression and hemorrhagic alveolar edema (r = 0.20, p = 0.034), marked diffuse alveolar edema (r = −0.20, p = 0.034), pulmonary emphysema (r = −0.36, p = 0.001), pleuritis (r = −0.55, p < 0.001), and pleural adhesions (r = −0.50, p < 0.001). Here, ICAM1 is linked to edema.
