Comparative intergroup analysis of mean optical density in pulmonary vascular endothelium in groups of patients with/without thrombotic complications.

Parameter	Patients without Thrombotic Complications	Patients with Thrombotic Complications	p-Value (Mann–Whitney U-Test)
Mean optical density in arteries	0.45 (IQR, 0.39–0.52)	0.48 (IQR, 0.41–0.58)	<0.001 *
Mean optical density in veins	0.46 (IQR, 0.39–0.56)	0.52 (IQR, 0.45–0.61)	<0.001 *
Mean optical density in arterioles	0.42 (IQR, 0.37–0.50)	0.43 (IQR, 0.37–0.53)	0.601
Mean optical density in venules	0.48 (IQR, 0.43–0.55)	0.51 (IQR, 0.42–0.59)	0.358
