Figure 3 Relationship between the mean of the maximum and minimum common carotid intima-media thickness values (IMT_mean) and the interadventitial diameter (IAD) (top panel), and IMT_mean and the ratio of IAD to the luminal diameter (LD) (bottom panel) in acute coronary syndrome patients. A significant positive correlation exists between IMT_mean and IAD, and IMT_mean and the ratio of IAD to LD.
