Fig. 2From: Vascular inflammation and aortic stiffness: potential mechanisms of increased vascular risk in chronic obstructive pulmonary diseaseMean tissue-to-blood ratio (TBR) in each of the aortic regions and carotid artery. a. Thoracic aorta, b. Abdominal aorta, c. Whole aorta, d. Carotid artery. Bars represent mean values and error bars represent 95% CI. Overall significance for each model was p < 0.001. Pairwise comparisons are illustrated by *p < 0.001 compared to never smokers, † p < 0.001 compared to smokers, ‡p < 0.01 compared to α1ATD patientsBack to article page
