Spectacular shrinking deficit followed by delayed Hemichorea-Hemiballismus: Redefining the stroke-TIA spectrum.
Article in eNeurologicalSci, 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
Spectacular shrinking deficit (SSD) is an exceptionally rare cerebrovascular phenomenon defined by the rapid and near-complete resolution of severe neurological deficits following major hemispheric ischemia. We present the first documented case of SSD manifesting as hemichorea-hemiballismus syndrome-a striking and clinically distinct presentation that challenges current understanding of stroke sequelae. A 59-year-old diabetic female developed violent, involuntary left-sided movements one week after transient left hemiplegia, which resolved spontaneously. Neuroimaging revealed T1 hyperintensities in the right striatum without contrast enhancement, subtle diffusion abnormalities, and focal right MCA stenosis, while metabolic workup ruled out hyperglycemic chorea. The patient's refractory symptoms responded uniquely to tetrabenazine, further supporting an ischemic rather than metabolic etiology.
