Figure 1 Survival. A, Cumulative all-cause survival. B, Univariate analysis revealed a significant difference in the cumulative survival between patients with an aortic diameter ≥41 mm and patients with an aortic diameter <41 mm (P = .012). Kaplan–Meier estimates are presented in Table 1. C, Survival stratified by diameter and age. D, Multivariate Cox regression analysis.

Figure 2 Treatment failure. A, Overall failure of conservative treatment. B, Failure of treatment stratified by diameter class revealed a significantly higher rate in patients with an aortic diameter ≥41 mm (P = .09; HR, 2.93). Kaplan–Meier estimates are presented in Table 2.
