  Figure 1. Kaplan–Meier estimator for patient survival. (A) Kaplan–Meier estimator for overall patient survival for the entire study cohort. 30-day,12-month and 5-year patient survival rates are depicted. (B) Kaplan–Meier estimator for patient survival following open repair (OR) and endovascular aortic repair (EVAR) for ruptured abdominal aortic aneurysm (rAAA). EVAR was found to have an early benefit for patient survival vs. OR, which disappears during the follow-up. 30-day, 12-month and 5-year patient survival rates are depicted. (C) Kaplan–Meier estimator for patient survival following EVAR or OR from 1993–2002 (G1-OR), 2003–2012 (G2-OR) or 2013–2022 (G3-OR). No difference was found for patient survival following OR between the different decades (p2), while EVAR was found to have an early survival benefit. 30-day, 12-month, and 5-year patient survival rates are depicted for all subgroups (p1). Breslow test was applied. * p < 0.05.

  Figure 2. Kaplan–Meier estimator for patient survival for different age groups. (A) Kaplan–Meier estimator for patient survival by age group in the setting of OR or EVAR treatment for rAAA. Patient survival was better in the <70 age group vs. ≥70 age group regardless of the surgical care performed. 30-day, 12-month and 5-year patient survival rates are depicted. (B) Kaplan–Meier estimator for patient survival of those <70 and ≥70 years of age, respectively, for surgical care performed. The OR group showed better patient survival in the <70 age group vs. ≥70 age group (p1); this difference was not detectable in the EVAR group for the same sub-groups (p2). In the cohort of patients ≥70 years of age, there was a survival advantage for patients treated by EVAR vs. OR (p3); this advantage was not shown for patients <70 years of age for the same sub-groups (p4). 30-day, 12-month, and 5-year patient survival rates are depicted. The Breslow test was applied. * p < 0.05.

  Figure 3. Kaplan–Meier estimator for sex-specific patient survival following open repair (OR) or endovascular aortic repair (EVAR) for ruptured abdominal aortic aneurysm (rAAA). The Kaplan–Meier estimator showed no sex differences in patient survival for the overall cohort regardless of the method used. 30-day, 12-month and 5-year patient survival rates are depicted. The Breslow test was applied.
