Ensuring Reproducibility in Endovascular Aneurysm Repair: Clinical Impact of Prophylactic Branch Embolization in a Low-Volume Setting.
Article in Annals of vascular diseases, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objectives: Although prophylactic branch embolization is known to reduce Type II endoleak after endovascular aneurysm repair (EVAR), its reproducibility and clinical value in low-volume regional centers remain under-discussed. This study evaluated the efficacy of an anatomy-guided embolization strategy for improving long-term sac behavior. Methods: This retrospective, single-center cohort study included 132 patients who underwent elective EVAR. Prophylactic embolization (Coil+ group, n = 30) was performed based on standardized anatomical criteria, while 102 patients underwent standard EVAR (Coil- group). Preoperative anatomical risks and mid-term clinical outcomes, including sac expansion and re-intervention rates, were compared. Results: Preoperatively, the Coil+ group showed significantly higher anatomical risk than the Coil- group, including a higher prevalence of a patent inferior mesenteric artery (IMA) (90.0% vs. 69.6%; Conclusions: Standardized prophylactic branch embolization was associated with durable sac stability. This proactive approach may offer a rational pathway for optimizing long-term outcomes, even in low-volume centers.
