Characteristics and Clinical Analysis of Dysphagia Caused by Pontine Infarction: A Video Fluoroscopic Swallowing Study.

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
objectiveTo investigate the characteristics of a video fluoroscopic swallowing study (VFSS) in patients with dysphagia caused by different parts of pontine infarction and to analyze the relationship between the severity of dysphagia and the parts of pontine infarction.
methodsThis study included 60 patients diagnosed with acute pontine infarction in the Department of Neurology and Rehabilitation Medicine of Handan Central Hospital from August 2022 to August 2023. Pontine infarction was divided into an upper pontine infarction group, middle pontine infarction group, and lower pontine infarction group according to the distribution characteristics of diffusion-weighted imaging (DWI). The VFSS evaluation results of patients with dysphagia brought on by infarction in different areas of the pons were calculated and analyzed to summarize the characteristics of dysphagia. The odified barium swallow impairment profile (MBSImP) was used to assess the severity of swallowing impairment in patients with pontine infarction at different locations.
resultsCompared with the upper and middle pontine infarction groups, the lower pontine infarction group was more prone to oropharyngeal swallowing disorder, and the incidence of lip closure, tongue control during bolus hold, oral residue, initiation of the pharyngeal swallow, laryngeal elevation, and tongue base retraction showed statistically significant differences among the three patient groups (p < 0.05). Compared with the suprapontine and middle infarct groups, the lower pontine infarct group had a higher MBSImP score in the oral and pharyngeal stages of swallowing disorders and a heavier degree of lip closure, tongue control during bolus hold, oral residue, initiation of the pharyngeal swallow, laryngeal elevation, and tongue base retraction, with statistical significance (p < 0.05).
conclusionPatients with subpontine infarction with dysphagia had relatively independent biological characteristics.
