Expanding the role of pneumatic dilation for nonachalasia patients: a comparative study.
Article in Gastrointestinal endoscopy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
BACKGROUND AND
aimsTreatment options for nonachalasia obstructive disorders of the esophagogastric junction (EGJ) are limited. The aim of this study was to assess the treatment efficacy of pneumatic dilation (PD) for the disorders of EGJ outflow obstruction (EGJOO) and postfundoplication EGJ obstruction (PF-EGJO) and to assess attitudes regarding training in PD.
methodsThis was a 2-part study. The main study was a prospective, single-center study comparing treatment outcomes after PD in patients with EGJOO and PF-EGJO, defined using manometry criteria, versus achalasia. Treatment success was defined as a post-PD Eckardt score (ES) of ≤2 at the longest duration of follow-up available. In a substudy, a 2-question survey was sent to 78 advanced endoscopy fellowship sites in the United States regarding training in PD.
resultsOf the 58% of respondents to the advanced endoscopy program director survey, two-thirds reported no training in PD at their program. The primary rationale cited was lack of a clinical need for PD. Sixty-one patients (15 achalasia, 32 EGJOO, and 14 PF-EGJO) were included in the main study with outcomes available at a mean follow-up of 8.8 months. Overall, mean ES decreased from 6.30 to 2.89 (P < .0001), and a mean percentage of improvement in symptoms reported by patients was 55.3%. ES ≤2 was achieved by 33 of 61 patients (54.1%).
conclusionsPD is an effective treatment for the nonachalasia obstructive disorders of the EGJ. There may be a current gap in training and technical expertise in PD.
