Figure 2. Decline in risk of stroke or death over time – unadjusted model.

Figure 2.

Modelled risks of stroke or death occurring within 30 days after treatment over time by treatment group in the unadjusted generalized linear mixed-effects model. Open and closed circles represent fitted values from the model. Error bars represent Bayesian 95% credible intervals. The interaction between type of treatment and year of treatment was statistically significant (interaction p=0.031). CEA – carotid endarterectomy; CAS – carotid artery stenting.
