Utility of High-Resolution Esophageal Manometry in the Evaluation of Presumed Oropharyngeal Dysphagia.

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: Evaluate the utility of high-resolution esophageal manometry (HREM) in patients with symptoms of oropharyngeal dysphagia (OD) but unremarkable Modified Barium Swallow Studies (MBSS). Study Design: Retrospective cohort study. Setting: Tertiary academic center. Methods: A retrospective review was conducted on patients with symptoms of oropharyngeal dysphagia from January 2021 to December 2024. Demographics, symptoms, and Charlson Comorbidity Index scores were recorded. Patients with unremarkable MBSS then underwent HREM. HREM data based on the Chicago Classification V 3.0 were analyzed, including mean residual upper esophageal sphincter (UES) pressure, median lower esophageal sphincter (LES) pressure, and ineffective swallow rates, using Results: Among 29 patients (mean age 53.2 years, 48.7% female), HREM findings showed mean residual UES pressure of -0.5 mmHg, median residual LES pressure of 13.9 mmHg, and 22.9% ineffective swallows. Esophageal pathologies (ineffective esophageal motility or esophagogastric junction outflow obstruction) were identified in 58.6% of cases. Symptom-specific differences in esophageal motility disorders were not statistically significant. Conclusion: HREM identified esophageal pathologies in 58.6% of patients with OD symptoms and normal MBSS, highlighting its value in the diagnostic workup of oropharyngeal dysphagia. The overlap of symptoms between oropharyngeal and esophageal motility disorders supports integrating HREM for comprehensive evaluation. Level of Evidence: 4.
