Correlation Between Peak Upper Esophageal Sphincter and Pharyngeal Pressures in Patients With Dysphagia.
Article in Laryngoscope investigative otolaryngology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Objective: The upper esophageal sphincter (UES) serves multiple functions in the management of the upper aerodigestive tract. Prior investigations have defined the roles of UES resting and nadir pressures in normal swallowing. The distinctly high-amplitude UES peak pressures, a patterned feature of pressure propagation in the transition from the pharynx to the esophagus on high-resolution manometry (HRM), have not been characterized beyond normative data reports. This study investigated the relationship between peak UES and pharyngeal pressures at the velopharyngeal and tongue base regions in both patients with dysphagia and healthy controls. Methods: Sixty-three adult patients with dysphagia underwent pharyngeal HRM to obtain peak measures of velopharyngeal, tongue base region, and UES pressures. Age- and sex-matched healthy controls were analyzed for comparison. Results: UES peak pressures in patients with dysphagia showed no significant correlation with velopharyngeal or tongue base region pressures ( Conclusions: Pharyngeal and UES peak pressures are correlated in healthy subjects; loss of this relationship in patients with dysphagia indicates that UES peak pressures may be influenced by factors independent of pharyngeal contractile responses and bolus-related sensory feedback. Level of Evidence: 4.
