Association Between Oral and Pharyngeal Functions in Patients in Medical-Dental Cooperation at an Acute Hospital.
Article in Journal of oral rehabilitation, 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
backgroundRecent studies have focused on oral frailty and hypofunction, and their relationship with swallowing function and dysphagia. These play especially important roles in patients with dysphagia in medical-dental cooperation at acute hospitals.
objectiveThis study aimed to assess oral frailty, in terms of nutritional intake by evaluating oral and swallowing functions simultaneously, in patients consulting at an acute hospital.
methodsThis cross-sectional study was conducted at the Center for Dysphagia of Tohoku University Hospital and involved a comprehensive survey of 183 patients. Their oral function and oral status were evaluated, which included factors such as poor oral hygiene, oral dryness, tongue-lip motor function, tongue pressure, and masticatory performance. Additionally, swallowing status was evaluated using various methods, including a questionnaire related to swallowing, Hyodo-Komagane score, modified water-swallowing, and repetitive saliva swallowing tests. This thorough approach ensured the validity and reliability of our findings.
resultsApproximately 60% of patients had head and neck tumours, degenerative diseases, and muscular diseases. Therefore, a high prevalence of oral hypofunction was observed. Furthermore, since 41.5% of patients had limited tongue movement, a characteristic correlation existed between the oral diadochokinesis and Hyodo-Komagane score.
conclusionThese results suggest that oral dryness score, oral diadochokinesis, and tongue pressure are associated with oral hypofunction and dysphagia. Additionally, patients with hypofunction and decreased tongue pressure may have hypopharyngeal residuals. The medical-dental cooperation in an acute hospital allows for the simultaneous assessment of oral and swallowing functions. This suggests a potential to contribute to the practice of safe oral intake and appropriate rehabilitation.
