Swallowing Muscle Ultrasonography in Children With Cerebral Palsy and Dysphagia: A Cross-Sectional Study.
Article in Laryngoscope investigative otolaryngology, 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
Objectives: To determine whether the thickness of swallowing-related muscles measured by ultrasonography (US) differs according to dysphagia status in children with cerebral palsy (CP) and to identify muscle-specific associations between US measurements and swallowing symptoms. Methods: In this cross-sectional study, 66 children with CP aged 2-18 years were evaluated at a tertiary outpatient rehabilitation clinic. B-mode US was used to measure the thickness of swallowing-related muscles. Symptom-defined dysphagia was defined as a Pediatric Eating Assessment Tool-10 (Pedi-EAT-10) score of ≥ 4. Muscle thicknesses were compared between children with and without dysphagia. Associations between individual Pedi-EAT-10 items and muscle thickness measurements were explored using Spearman correlation and univariate linear regression analyses. Results: Of the 66 children, 27 (40.9%) met the criteria for dysphagia. US-measured muscle thickness did not differ significantly between children with and without dysphagia for the masseter (0.66 ± 0.12 vs. 0.68 ± 0.10 cm; Conclusions: Although swallowing-related muscle thickness did not differ between children with CP with and without dysphagia, US measurements were associated with specific caregiver-reported swallowing complaints. These findings suggest that US may provide complementary, symptom-oriented information in the clinical assessment of swallowing difficulties in children with CP.
