Fig 1 Kaplan-Meier survival for (A) 445 patients ≤50 years old who underwent thoracoabdominal aortic aneurysm repair and (B) patients stratified into two groups: those with connective tissue disorder (CTD) (n = 237) and those without CTD (n = 208). Because age differed between those with CTD (mean age, 36.1 years) and those without (mean age, 42.5 years), a Cox regression model was used to adjust for age; nevertheless, no significant difference in survival was found between groups (p = 0.1). (C) Kaplan-Meier freedom from repair failure for the 3,095 early survivors when stratified by age ≤50 years (n = 431) and age >50 years (n = 2,664).
