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 Aims: In patients with achalasia treated via Heller myotomy (HM) or peroral endoscopic myotomy (POEM), incomplete myotomy can lead to a "blown-out myotomy" (BOM) diverticulum, worsening obstruction, and dysphagia. We present peroral direct diverticulotomy (PODD), a salvage technique, similar to the "ultrashort tunnel" Zenker's peroral endoscopic myotomy technique, targeting the residual sphincter at the diverticular septum. Methods: We performed PODD in a 49-year-old man with type I achalasia who underwent POEM with minimal relief (Eckardt score 4). At 18 months, the esophagram showed delayed emptying, incomplete myotomy, and BOM diverticulum, and endoscopy revealed a "puckered," tight lower esophageal sphincter (LES) and a BOM diverticulum. PODD achieved a 2-cm myotomy at the diverticular septum, completing the initial myotomy. Results: The 25-minute procedure was uneventful, and the patient was discharged after 23 hours. Four-week follow-up endoscopy showed patulous LES, resolution of the septum, and no reflux esophagitis. Endoluminal functional lumen imaging probe and esophagram were consistent with resolution of obstruction. At 6 months, swallowing was improved (Eckardt score 1) with no gastroesophageal reflux disease symptoms. Conclusions: As POEM spreads to low-volume centers, BOM diverticula-once mainly seen after failed HM-are increasingly seen after POEM. PODD offers a technically simple, effective salvage technique with potential broad applicability in managing POEM and HM failure due to BOM.
