Delayed Saphenous Vein Graft Rupture Secondary to Mediastinal Abscess: A Case Report.
Article in Cureus, 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
Saphenous vein graft (SVG) rupture is a rare but catastrophic late complication of coronary artery bypass grafting (CABG). We report a 73-year-old male who presented five years after CABG and thoracic aortic aneurysm repair and was found to have a mediastinal fluid collection surrounding the ascending aorta. Emergent surgical exploration under hypothermic circulatory arrest revealed dehiscence of the SVG at its aortic anastomosis with associated mediastinal hemorrhage and evidence of infection at the graft site. The patient required postoperative pharmacologic hemodynamic support and extended antimicrobial therapy for mediastinal infection, followed by gradual clinical recovery. This case highlights the diagnostic challenge and rapid progression of late SVG dehiscence and underscores the importance of early recognition of this rare complication in post-CABG patients presenting with new mediastinal abnormalities.
