Handgrip strength and the Index of pulmonary dysfunction: Practical screening tools for cough dysfunction in huntington's disease.
Article in Journal of Huntington's disease, 2026. 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
BackgroundAs Huntington's disease (HD) progresses, it impairs airway protection, increasing the risk of aspiration pneumonia-the leading cause of death in HD. Although voluntary peak cough flow (vPCF) assesses cough effectiveness, its clinical use is limited by time and equipment constraints.ObjectiveThis study evaluates handgrip strength (HGS) and the Index of Pulmonary Dysfunction (IPD) as simpler screening tools and aims to define gender-specific thresholds for identifying cough dysfunction (dystussia) in HD patients.MethodsIn this prospective cross-sectional study, 71 patients with HD underwent assessments of HGS, IPD, vPCF, respiratory muscle strength, and were rated using the Unified Huntington's Disease Rating Scale. Logistic regression and ROC analyses were used to assess the predictive value of HGS and IPD for dystussia (vPCF <300 L/min).ResultsAmong 32 females and 39 males, 30 exhibited dystussia and had more advanced disease. HGS showed AUCs of 0.82 (females) and 0.89 (males), IPD 0.86 overall. Combining HGS and IPD improved accuracy.ConclusionsHGS and IPD appear to be effective tools for initial dystussia screening in HD.Trial registrationNCT06585332.
