"Gol-Gappa" Dystonia - A Novel Form of Focal Task-Specific Dystonia.
Article in Tremor and other hyperkinetic movements (New York, N.Y.), 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
Background: Task-specific dystonias (TSDs) are focal movement disorders triggered by highly repetitive, skilled motor tasks, often within profession-specific contexts. Although upper limb TSDs are well documented, culturally unique forms continue to emerge. Case Report: We present a case of a 30-year-old right-handed male who developed focal dystonia exclusively while preparing Gol-gappa (paani puri), an Indian street food requiring repetitive, precise hand movements to fill puris with spiced stuffing. Neurological examination and neuroimaging were unremarkable. Electromyography guided botulinum toxin injections into affected forearm and hand flexors resulted in approximately 70% improvement in task performance within two weeks. Discussion: Gol-gappa dystonia represents a novel, culturally specific variant of occupational TSD. This case broadens the recognized spectrum of task-specific dystonias and supports the role of targeted botulinum therapy as an effective intervention.
