Atrial myxoma-related embolic stroke: two distinct embolic mechanisms and clinical implications in young adults (a case series).
Article in BMC neurology, 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
backgroundCardiac myxoma can lead to stroke via two distinct embolic mechanisms: embolism from tumor fragments or thromboembolism from the tumor surface. Pathological confirmation of the embolus is rarely conducted; however, the pathological features of stroke have implications for treatment. CASE SERIES REPORT: We present two young Chinese patients with acute ischemic stroke subsequent to atrial myxoma, whose stroke was caused via distinct embolic mechanisms. The first patient exhibited isolated basilar artery occlusion due to secondary thrombosis. This patient underwent successful computed tomography(CT)-guided mechanical thrombectomy 11 h after symptom onset. The second patient exhibited the combination of cerebral and peripheral embolism due to direct shedding of tumor emboli and was subjected to sequential endovascular treatment. Both patients achieved complete recanalization and favorable 3-month functional outcomes after tumor resection. These cases highlight phenotypic heterogeneity, differences in embolic mechanisms, and the value of integrated imaging, pathological examination, cardiac assessment, and individualized therapy in atrial myxoma-related stroke.
conclusionAtrial myxoma-associated strokes involve two distinct mechanisms of embolism that may affect secondary prevention and follow-up strategies. Accurate differentiation relies on the pathological examination of embolic material, which requires coordinated multidisciplinary care to develop personalized treatment.
