Mitral-Aortic Intervalvular Fibrosa Pseudoaneurysm: A Rare and Life-Threatening Presentation.
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
A 40-year-old male with no prior history of cardiac disease or other comorbidities presented to the emergency department with a history of high-grade intermittent fever and breathlessness for two weeks. Examination revealed a febrile patient who had features of mitral regurgitation and aortic regurgitation. A transthoracic echocardiogram (TTE) revealed vegetation in the anterior mitral leaflet, along with moderate aortic and mitral regurgitation and a ruptured aortic root abscess that formed dual fistulous tracts in the aortic root. An extremely uncommon complication of infective endocarditis affecting the aortic valve is the development of an abscess in the intervalvular fibrosa (IVF) dual fistula formation. A dual fistulous tract communicating with the aortic root and the ascending aorta is very sparsely described in the literature. A 64-slice computed coronary angiography confirmed a pseudoaneurysm posterior to the aortic root, communicating with the aortic root through a neck and with the left ventricular outflow tract.
