The Role of Handedness and Extrainstrumental Burdens on the Course of Musicians' Dystonia.
Article in Journal of movement disorders, 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
objectiveThis study investigated the impact of extrainstrumental workload on musician's dystonia (MD) and its relationship with playing ability by testing whether dystonia onset is more severe in the dominant hand and whether improvement during treatment depends on which hand is affected, the dominant or nondominant.
methodsA total of 151 patients with dominant-hand MD and 92 with nondominant hand MD were assessed for their ability to play at dystonia onset (T0) and after treatment (T1).
resultsThere was no significant difference in playing ability at onset between the groups. Significant improvement and a greater change in playing ability were observed in the dominant-hand group. We found no difference in the proportional frequency of right-handed and left-handed individuals in the group of patients affected on the right or left side, respectively.
conclusionThese findings suggest that handedness does not influence MD localization, but the prognosis is more favorable for those with dominant hand dystonia, potentially due to metaplasticity effects.
