Figure 1. Cumulative incidence of death with TEVAR and open surgical repair.
The difference in mortality between open surgical repair and TEVAR was statistically significant by the log-rank test, p <0.001. Additionally, the difference in restricted mean survival time was significant: −209.2 days (95% CI −298.7 to −119.7 days; p <0.001) suggesting that there was a substantial survival disadvantage with open surgical repair.
