Fig 1 A Kaplan-Meier analysis of type I endoleaks between four eras compared by a log-rank test with Scheffe correction for multiple comparisons. Total at risk, N = 1378; era 1, n = 116; era 2, n = 524; era 3, n = 526; era 4, n = 212; overall, P = .48. The standard error did not exceed 10%.

Fig 2 A Kaplan-Meier analysis of type II endoleaks between four eras compared by a log-rank test with Scheffe correction for multiple comparisons. Total at risk, N = 1378; era 1; n = 116; era 2, n = 524; era 3, n = 526; era 4, n = 212; overall, P < .0001. No difference was observed between era 1 and era 2. Statistically significant differences were observed between eras 1 and 3 or 4. Statistically significant differences were observed between eras 2 and 3 or 4. For era 1, the standard error exceeded 10% at 7.5 years and 10 years, where the standard error is 15%.
