Association of alcohol responsiveness and non-motor symptoms in isolated adult-onset dystonia.
Article in Journal of neurology, 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
objectiveAbout 30% of patients with isolated adult-onset dystonia report an improvement of their motor symptoms after the consumption of alcohol. In this cross-sectional study, we sought to investigate whether the observed improvement is attributable to the anxiolytic, euphoric, and analgesic properties of alcohol, rather than or in addition to its effect on dystonic movements, as psychiatric symptoms and pain frequently occur in dystonia patients and as emotional stress is a well-established trigger for symptom exacerbation.
methodsWe analyzed data from 339 prospectively enrolled participants with recently diagnosed isolated dystonia (mean age: 55.2 ± 12.5 years, 228 female) of the Natural History Project of the Dystonia Coalition, a large international multicenter study. Alcohol responsiveness was determined by patients´ self-report. Symptoms of depression, as well as generalized and social anxiety, were assessed using the Hospital Anxiety and Depression Scale and the Liebowitz Social Anxiety Scale. Severity of pain was measured using question 21 of the RAND 36-Item Health Survey.
resultsParticipants with more severe pain reported greater response to alcohol than those with less severe pain (p = .004), whereas symptoms of depression (p = .986), generalized anxiety (p = .395) and social anxiety (p = .953) were not associated.
conclusionAlcohol responsiveness in isolated dystonia is associated with higher levels of pain, whereas self-reported alcohol-related improvements in dystonic movements or tremor do not depend on the euphoric or anxiolytic effects of alcohol. This finding underscores the potential role of pain management in alleviating motor symptoms in dystonia.
