Treatment procedures for intractable gastroesophageal reflux disease after peroral endoscopic myotomy for achalasia: a retrospective study in South Korea.
Article in Clinical endoscopy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundNo study has compared the safety and efficacy of anti-reflux mucosal ablation (ARMA), anti-reflux mucosectomy (ARMS), and Stretta radiofrequency (SRF) for intractable gastroesophageal reflux disease (GERD) after peroral endoscopic myotomy (POEM).
methodsTwenty-two patients with post-POEM GERD underwent either ARMA (n=12), ARMS (n=6), or SRF (n=4). GERD questionnaire (GERDQ) score, endoscopic Los Angeles classification, flap valve grade based on Hill's type EndoFLIP distensibility index (DI), and rate of proton pump inhibitor withdrawal were analyzed and compared. The factors associated with the occurrence of post-POEM intractable GERD were also evaluated.
resultsThe ARMS group demonstrated a significant improvement in GERDQ scores after 6 months of follow-up (p=0.04). No significant differences were observed in the endoscopic Los Angeles grade (p=0.68), flap valve grade (p=0.38), or EndoFLIP DI (p=0.15). Type III achalasia and posterior myotomy orientation during POEM were identified as risk factors for reintervention. Postprocedural adverse events (bleeding and stricture) occurred in the ARMA and ARMS groups.
conclusionsAmong the three procedures, ARMS produced the most notable improvement in symptoms, whereas endoscopic esophagitis and EndoFLIP DI did not show a similar improvement.
