Ultrasonographic assessment of dysphagia in Parkinson's disease: a controlled study.
Article in Neurological sciences : official journal of the Italian Neurological Society and of the Italian Society of Clinical Neurophysiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundSwallowing dysfunction is a common but often overlooked symptom in Parkinson's disease (PD), significantly affecting patients' quality of life. Ultrasonography has emerged as a promising, non-invasive, radiation-free, and dynamic assessment tool for evaluating swallowing function in PD.
aimsThis study aimed to dynamically assess swallowing function in early- and mid-stage Parkinson's disease patients using ultrasonography and compare the findings with healthy controls.
methodsThis cross-sectional study included 30 patients diagnosed with PD and 30 healthy volunteers. Swallowing function was assessed using the Eating Assessment Tool-10 (EAT-10) questionnaire. Ultrasonographic measurements at rest, dry swallowing, and 5 mL water swallowing evaluated tongue thickness, mandible-hyoid distance(MHD), and hyoid displacement. Parkinson's disease severity was assessed using the Modified Hoehn-Yahr (HY) Scale and the Movement Disorders Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS).
resultsEAT-10 scores were significantly higher in the PD group compared to healthy controls (p < 0.001), with 43.33% of patients exhibiting clinically significant dysphagia (EAT-10 ≥ 3). During dry swallowing, minimum MHD was significantly higher (p < 0.05), while hyoid displacement distance (p = 0.013) and percentage (p = 0.002) were significantly lower in PD patients. Similarly, during 5 mL water swallowing, hyoid displacement percentage was significantly lower in the PD group (p = 0.019). No significant correlation was found between ultrasonographic measurements and disease severity (HY staging, MDS-UPDRS scores).
conclusionUltrasonography is a valuable tool for assessing swallowing dysfunction in PD, revealing reduced hyoid displacement even in early stages. The high prevalence of dysphagia supports routine swallowing assessments. Ultrasonography integration may aid early detection, improving patient outcomes and reducing aspiration-related risks.
