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
backgroundHuntington's disease (HD) is an autosomal dominant neurodegenerative disorder caused by a mutation in the huntingtin gene on chromosome 4, leading to progressive cognitive decline, motor impairment, and functional disability. Although balance impairment is recognized in HD, its onset and evolution with disease stage remain poorly understood.
objectiveThe aim was to track the onset and evolution of balance impairment in HD with progression of disease stage using the BTrackS Balance Plate.
methodsTotal body sway (TBS) was assessed in 123 gene-positive participants and 33 healthy controls (HC) using the BTrackS Balance Plate and laptop software. The prognostic index-derived Huntington's Disease Integrated Staging System (HD-ISS) was used to stratify these subjects into stage 0/1 (n = 51), stage 2 (n = 38), and Stage 3 (n = 34). Nonparametric receiver operating characteristic curve analysis was used to compute optimal cutoff values for TBS.
resultsBalance assessment revealed significant differences in TBS between HCs and gene-positive participants (P < 0.001). TBS varied significantly across disease stages (P < 0.001), with mean values of 9.56 cm (stage 0/1), 14.46 cm (stage 2), and 28.26 cm (Stage 3). The comparison between HCs and stage 0/1 individuals revealed strong discrimination (area under the curve [AUC] = 0.709), with a threshold of 7.72 cm achieving 74.5% sensitivity. The most robust discrimination emerged between stage 2 and Stage 3 participants (AUC = 0.71), with a threshold of 11.85 cm at 82.4% sensitivity.
conclusionsIn conclusion, this cross-sectional study demonstrates that balance impairment is an early and progressive feature of HD, detectable even before the onset of overt motor symptoms.
