Subarachnoid hemorrhage as the initial imaging finding of atrial-esophageal Fistula: a case report highlighting diagnostic challenges.
Article in Frontiers in cardiovascular medicine, 2025. 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
Atrial-esophageal fistula (AEF) is a rare but life-threatening complication after catheter ablation. Neurological deficits represent the second most common clinical manifestation associated with AEF; however, diagnosis is often delayed because initial symptoms can be atypical and easily overlooked. Here we reported a case involving a 51-year-old male who presented with fever and headache three weeks after catheter ablation for atrial fibrillation. Initial cranial computed tomography (CT) showed right frontal subarachnoid hemorrhage (SAH) without aneurysm. As the patient's condition deteriorates, repeated imaging demonstrates worsening SAH, cerebral air emboli, and air signals in the left atrium. This case highlights the importance of considering AEF in patients with neurological deficits and recent cardiac ablation, even when initial imaging findings are atypical.
