Unrecognized Atrial Septal Defect Presenting with Postoperative Occipital Infarction.
Article in Diagnostics (Basel, Switzerland), 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 49-year-old woman developed acute homonymous hemianopia three days after elective surgery. Neuroimaging confirmed an embolic right occipital infarction. Transthoracic echocardiography demonstrated early bubble passage, and transesophageal imaging identified a 4.6 mm ostium secundum atrial septal defect. The defect was successfully closed percutaneously with complete shunt resolution. This case emphasizes the value of targeted multimodality imaging in uncovering occult interatrial shunts and highlights presumed paradoxical embolism as a potential mechanism of postoperative or cryptogenic stroke.
