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
A 100-year-old male patient was admitted with a ruptured abdominal aortic aneurysm due to type IA endoleak. Given the proximity of the ruptured site to the superior mesenteric artery (SMA) and renal arteries, a ChEVAR was indicated. Catheterization of the target visceral vessels was a challenging procedural step because of an intensely tortuous thoracic aorta. This hostile aortic anatomy also inhibited exchange for a super stiff guide-wire and selective cannulation with the diagnostic catheter was repeatedly lost when guidewire exchange was attempted. To overcome this issue, a 5 x 40 mm balloon catheter was placed 3cm into the target arteries. The balloon was then inflated below the nominal pressure limit enabling safe exchange for a super stiff guidewire and placement of three 90-cm long 7Fr guiding sheaths. The procedure was thus safely performed with deployment of an aortic extension and the bridging stents.
