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
backgroundIntravascular lithotripsy (IVL) is an emerging technique for modifying heavily calcified arterial lesions, with primary application in peripheral arteries. We report the use of IVL for lesion preparation prior to stenting in a patient with severely calcified superior mesenteric artery (SMA) stenosis. CASE PRESENTATION: A 66-year-old man with type I adenocarcinoma of the esophagogastric junction (AEG Type I) and neoadjuvant FLOT chemotherapy was scheduled for Ivor Lewis esophagectomy. Preoperative CT angiography (CTA) revealed a high-grade ostial SMA stenosis due to extensive atherosclerotic calcification. To mitigate the risk of postoperative mesenteric hypoperfusion, percutaneous endovascular revascularization was performed. Following initial predilatation, IVL using a Shockwave 5.5 × 60 mm balloon catheter was employed for lesion preparation. Subsequently, an 8.0 × 24 mm balloon-expandable stent was successfully deployed with low-grade residual stenosis and no complications.
conclusionThis case demonstrates that IVL represents a feasible and effective adjunct in the management of severely calcified visceral arterial lesions. It facilitates adequate lesion preparation and enables full stent expansion, even when the IVL balloon diameter is notably smaller than the stent diameter. This potentially represents a less traumatic approach to the vessel than alternative techniques. IVL may therefore be considered a therapeutic option in selected patients.
