Reduced Long‐Term Risk of Aortic Aneurysm and Aortic Dissection Among Individuals With Type 2 Diabetes Mellitus: A Nationwide Observational Study

Figure 1. A Kaplan‐Meier survival curve presenting unadjusted cumulative incidence rate of aortic aneurysm in individuals with type 2 diabetes mellitus (T2DM) vs population‐based matched control subjects. Crude incidence rates were calculated as events per 100 000 person‐years.

Figure 2. A Kaplan‐Meier survival curve presenting unadjusted cumulative incidence rate of aortic dissections in individuals with type 2 diabetes mellitus (T2DM) vs population‐based matched control subjects. Crude incidence rates were calculated as events per 100 000 person‐years.

Figure 3. A Kaplan‐Meier survival curve presenting unadjusted estimated survival among individuals with type 2 diabetes mellitus (T2DM) vs population‐based matched control subjects (CSs) after an event of aortic aneurysm (AA). Crude incidence rates were calculated as events per 100 person‐years. Regression analysis was performed on the data set. It found significant adjusted risk reduction of 12% (hazard ratio [HR], 0.88; 95% confidence interval (CI), 0.82–0.94; P<0.0001) for mortality after AA, and unaltered risk (HR, 1.07; 95% CI, 0.85–1.34) for mortality after aortic dissection, up to 2 years, among the T2DM group, compared with CSs.
