Unusual blue discolouration of the ascending aorta in a patient with Churg-Strauss syndrome undergoing surgical aortic valve replacement: a case report.
Article in Journal of surgical case reports, 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
Churg-Strauss syndrome (eosinophilic granulomatosis with polyangiitis) is a rare systemic vasculitis that predominantly affects small- to medium-sized vessels, with large-vessel involvement being exceptional. We report a 72-year-old woman with Churg-Strauss syndrome and severe low-flow, low-gradient aortic stenosis (left ventricular ejection fraction 15%) who underwent surgical aortic valve replacement following multidisciplinary Heart Team assessment. Intraoperatively, an unusual blue discolouration of the ascending aortic intima was observed. Postoperatively, the patient developed cardiac tamponade requiring urgent reintervention and had a prolonged recovery before being discharged to rehabilitation. This case expands the spectrum of vascular manifestations in Churg-Strauss syndrome and highlights potential perioperative challenges during cardiac surgery.
