Functional Lumen Imaging Probe Measurement Post-Pneumatic Dilation in Clinically Relevant Esophagogastric Junction Outlet Obstruction.
Article in Neurogastroenterology and motility, 2025. 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
backgroundPneumatic dilation (PD) is an effective treatment for disorders of reduced esophageal opening. Functional lumen impedance planimetry (FLIP) can effectively measure lower esophageal sphincter (LES) physiology compared to esophageal standards. The aim of this retrospective cohort analysis was to evaluate if FLIP measurements and esophageal opening classifications changed consistently with symptom improvement post-PD. Also, the aim was to determine if post-PD FLIP measurement correlated with the need for repeat dilation.
methodsPatients with clinically significant esophagogastric junction outlet obstruction (EGJOO) with reduced esophageal opening (REO) or borderline REO (BrEO) based on FLIP, timed barium esophagram (TBE), and manometry who underwent PD were included. Post-PD FLIP measurements were taken immediately after PD during the same endoscopy encounter.
resultsAfter PD, average distensibility index (DI) increased from 1.5 mm
conclusionsPD appears to be associated with improved esophageal opening and a significant change in both DI and diameter, consistent with an improved Eckardt score. Post-dilation DI, diameter, esophageal opening pattern, and Eckardt score did not reveal a trend indicating the need for repeat dilation.
