Figure 2. Predicting Aneurysm Repair by Diabetes in Men and Women.

a and b. Under the assumption of linear growth, we modeled the effect of a diagnosis of diabetes in a patient with a small aortic aneurysm assuming and initial diameter of 4.3 cm (median baseline diameter of patients enrolled in N-TA³CT) applying yearly median growth rates as calculated by linear regression. Aneurysm growth in those with a diagnosis of diabetes is represented by a red line and growth in those without a diagnosis of diabetes is represented by a blue line. The vertical black lines represent the points in time at which repair thresholds are projected to be met (5.5 cm in men and 5 cm in women).
