Caffeine Use in Huntington's Disease: A Single Center Survey.
Article in Tremor and other hyperkinetic movements (New York, N.Y.), 2024. 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: Anecdotal evidence suggests paradoxical caffeine overuse in individuals with Huntington's disease (HD). A small retrospective study associated caffeine intake over 190 grams daily to earlier onset of HD symptoms. However, specific data on consumption habits is limited. This study aims to gather pilot data on caffeine use in people with HD, exploring motivations and consequences. Methods: Thirty adults with HD completed a survey on daily caffeine intake, its impact on symptoms, and consumption motivations through multiple-choice and open-ended questions. Descriptive statistics were used to analyze findings and compare them to general population data. Results: Caffeine intake ranged from 0 to 1400.4 mg/day, with a median of 273.2 mg/day and a mean of 382.5 mg/day. Seventy percent of participants with HD consumed more caffeine than the average for their age group in the general population. Additionally, 20% of participants and 38% of family members believed caffeine influenced HD symptoms, primarily anxiety. Discussion: People with HD typically consume more caffeine than the general U.S. population. Contrary to the hypothesis, higher caffeine intake was not associated with significant subjective worsening of HD symptoms. Further research with objective measures and multiple HD centers is necessary to guide screening and counseling on caffeine use in this population. Highlights: Participants with Huntington's disease (HD) had increased caffeine intake compared to the general population, supporting previous anecdotal observations. Anxiety was the most affected HD symptom. Further research using objective measures of symptom burden and including multiple HD centers can help inform screening and counseling regarding caffeine use in this population.
