Comparative intergroup analysis of mean optical density in vascular endothelium in the groups of patients with PE and thrombosis.

Parameter	Patients with PE	Patients with Thrombosis	p-Value (Mann–Whitney U-Test)
Mean optical density in arteries	0.46 (IQR, 0.39–0.53)	0.52 (IQR, 0.43–0.60)	<0.001 *
Mean optical density in veins	0.48 (IQR, 0.41–0.57)	0.54 (IQR, 0.47–0.62)	<0.001 *
Mean optical density in arterioles	0.40 (IQR, 0.35–0.47)	0.54 (IQR, 0.44–0.62)	<0.001 *
Mean optical density in venules	0.48 (IQR, 0.39–0.61)	0.51 (IQR, 0.46–0.59)	0.120
