Acute Hemichorea in a Young Patient Secondary to Ischemic Infarction in the Right Lentiform Nucleus: A Case Report.
Article in Cureus, 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
Chorea is a hyperkinetic movement disorder characterised by brief, unpredictable, dance-like involuntary movements involving multiple body parts. Hemichorea is its unilateral variant, affecting one side of the body. Both can arise from diverse aetiologies, including genetic, vascular, metabolic, autoimmune, drug-induced, and infectious causes. We report the case of a 31-year-old male with no significant past medical history who developed sudden-onset, left-sided hemichorea and homonymous hemianopia. Brain MRI demonstrated an acute right lentiform infarct, predominantly involving the globus pallidus. The patient improved markedly within 24 hours following the initiation of antiplatelet therapy. Further investigations revealed a Stage 2A-shunt patent foramen ovale, deemed the likely aetiology. This case underscores the importance of recognising hemichorea as a rare but possible manifestation of acute ischaemic stroke and highlights the need for comprehensive diagnostic evaluation in young patients presenting with atypical stroke symptoms.
