Figure 2. Predicted Risk of Aortic Dissection Over 5 Years for Fixed and Increasing Thoracic Aortic Aneurysm (TAA) Size.

Estimated predicted 5-year cumulative incidence was based on fitted multivariable Cox models with time-dependent covariates, considering the case where TAA size remained constant over 5 years’ follow-up and where TAA size increased 1 category at 2 years.
