Step-Down Therapy Using Vonoprazan for Giant Gastric Polyps in Long-Term Proton Pump Inhibitor Administration.
Article in Case reports in gastroenterology. 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
Introduction: Gastroesophageal reflux disease (GERD) is diagnosed based on bothersome symptoms, such as heartburn, and the presence of mucosal breaks endoscopically. Treatments that suppress gastric acid, such as proton pump inhibitor (PPI) and vonoprazan, are frequently administered. Several studies reported regarding the safety and side effects of long-term PPI administration, including an association with gastric polyps. We report a case of maintained symptom resolution and significantly shrank gastric polyps by performing step-down therapy, which is minimal acid-suppressing treatment. Case Presentation: A female patient in her 60s had been taking PPI for reflux esophagitis for >10 years. An upper gastrointestinal endoscopy revealed two gastric polyps measuring 20 mm and 10 mm. She was referred to our hospital for resection, but narrow-band imaging revealed a nonneoplastic lesion. PPI was discontinued, and step-down therapy using vonoprazan was performed. During the treatment, a lifestyle guidance app (Muneyake PRO) was used to record daily heartburn symptoms, oral medication status, and daily life status. She was worried that her symptoms would worsen due to discontinuation, but she gained her understanding when the use of the app to monitor her symptoms was explained. The app was useful for understanding the progress of symptoms and the status of oral medication. Step-down therapy was performed only twice after PPI discontinuation, symptoms have not worsened, and follow-up endoscopy revealed significant gastric polyp shrinkage. Conclusion: We experienced a case in which minimal acid-suppression treatment and step-down therapy using vonoprazan resulted in GERD symptom control and significant gastric polyp shrinkage.
