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
Mixed reality-guided endovascular repair using physician-modified devices offers an innovative solution for urgent repair of complex abdominal aortic aneurysms. We present the first case treated in this manner in a 77-year-old man with a symptomatic infrarenal abdominal aortic aneurysm and hostile proximal neck. A three-dimensional aortic model obtained from computed tomography angiography was overlaid onto a Treo graft via a Meta Quest 3 headset for precise on-table ostial marking and fenestration. After modification and resheathing, the endograft was advanced using fusion and angiography guidance. The endograft was then deployed, demonstrating perfect matching between each fenestration and the target vessels. A final aortogram confirmed patency of visceral branches and absence of endoleak. Mixed reality guidance enables accurate, rapid customization when patient-specific company-manufactured devices are unavailable, offering a viable urgent alternative for fenestrated endovascular repair.
