From: Atherosclerotic plaques occur in absence of intima-media thickening in both systemic sclerosis and systemic lupus erythematosus: a duplexsonography study of carotid and femoral arteries and follow-up for cardiovascular events

Figure 2

Incidence and rate ratios of cardiovascular events during follow-up according to the presence of plaque. Incidence of cardiovascular events per 100 person-years (py) during follow-up available for 129/190 (67.9%) patients (650 person-years, mean 60.5 months, median 65.5 months, range 8 to 82 months) according to the presence of carotid and femoral artery plaque. The rate ratio (RR) was approximately 6.5 for patients with carotid and femoral artery plaque in contrast to patients with only one vascular segment affected and was 8.7 compared with patients without plaque. CI, confidence interval.
