Tetrabenazine-Responsive Choreo-Ballism and Akathisia After Cardioversion and Coronary Angiography: A Case Report.
Article in Cureus, 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
Hyperkinetic movement disorders after routine cardiac procedures are rare yet disabling and often misdiagnosed. We report the case of a 76-year-old man who developed abrupt, generalized choreo-ballism with severe akathisia one day after coronary angiography. Metabolic and inflammatory serum studies were unremarkable, brain magnetic resonance imaging (MRI) demonstrated no acute causative lesion, including no basal ganglia abnormality, and cerebrospinal fluid (CSF) analysis was non-inflammatory with negative infectious, autoimmune, and paraneoplastic testing. Low-dose tetrabenazine produced rapid (>80%) and sustained remission, permitting drug discontinuation after 16 months without relapse. When choreo-ballism emerges after cardiac interventions, transient basal ganglia dysfunction related to peri-procedural hypoxia or contrast neurotoxicity may be considered as a possible mechanism, and early vesicular monoamine transporter type 2 (VMAT-2) inhibition may facilitate recovery.
