Figure 1.
This Kaplan-Meier curve demonstrates the estimated probability of primary stent patency up to 3 years (n=76 stents). Overall, 9 stents -- 1 celiac, 6 renal, and 2 SMA – occluded. Seven of those occlusions (9%) occurred within three years. Accounting for patients with less than 3 years of follow-up, the estimated probability of primary patency at 3 years is 85% (95% CI: 75–95%). The standard error of the mean is <10% at all displayed intervals.
