Middle cerebral artery occlusion due to paradoxical embolism diagnosed by pulmonary artery thrombosis in the absence of deep vein thrombosis: A case report.
Article in Radiology 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
A definitive diagnosis of paradoxical embolism generally requires confirmation of an arterial embolic event, a right-to-left shunt, identification of a venous thrombus, and exclusion of other embolic sources. In clinical practice, pulmonary embolism may be identified even in the absence of detectable deep vein thrombosis. In the present case, paradoxical embolism was considered highly probable based on the identification of a pulmonary artery thrombus despite the absence of deep vein thrombosis. A 54-year-old woman underwent successful thrombectomy with subsequent neurological improvement. Repeated postoperative ultrasonography showed no evidence of deep vein thrombosis. Transesophageal echocardiography revealed a patent foramen ovale, and contrast-enhanced computed tomography identified a pulmonary artery thrombus in the absence of deep vein thrombosis. Anticoagulation therapy resulted in complete thrombus resolution without recurrence.
