Do cognitive tests capture symptoms that matter to people with Huntington's disease?
Article in Scientific reports, 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
The Huntington's Disease Cognitive Assessment Battery (HD-CAB) is frequently used in clinical trials; however, it is unclear whether the HD-CAB captures meaningful symptoms from patients' perspectives. We aimed to explore whether HD-CAB tests are considered meaningful to people with Huntington's disease (HD) by mapping them to relevant symptoms and impacts. Eighteen people with HD before and after clinical motor diagnosis completed a semi-structured interview with symptom mapping to hierarchically rank the importance and bothersomeness of cognitive symptoms and discussed the relevance of each test to meaningful symptoms. Reflexive Thematic Analysis (RTA) was used to explore participant perceptions of the relevance of HD-CAB tests for assessing disease progression. Content coding was used to identify the frequency of important symptoms and impacts, and we used binomial tests to determine whether there was statistically significant consensus (agreement > 50%). Our findings showed that all HD-CAB tests were viewed as meaningful by a significant majority of participants and all subtests were agreed to assess important or bothersome symptoms (p < .05). Participants identified two factors contributing to the importance of the HD-CAB tests for measuring HD changes: (1) The tests of the HD-CAB provide participants with knowledge about their abilities and disease; and (2) The tests of the HD-CAB capture changes that are important for everyday life. Overall, the HD-CAB was a meaningful cognitive assessment tool from the perspective of people with HD.
