Hypercontractile esophagus responsive to potassium-competitive acid blockers: a case report.
Article in BMC gastroenterology, 2022. 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
backgroundHypercontractile esophagus is a rare hypercontractile esophageal motility disorder. The etiology of hypercontractile esophagus is unknown but an association between acid reflux and hypercontractile esophagus has been suggested. We present the first report on the use of potassium-competitive acid blockers in the treatment of hypercontractile esophagus. CASE PRESENTATION: A 43-year-old man presented with dysphagia, chest pain and regurgitation for a period of 1 year. Initial workup showed a twisted lumen with abnormal contractions in the distal esophagus during upper gastrointestinal endoscopy and abnormal acid exposure under 24-h esophageal pH monitoring. The use of standard-dose proton pump inhibitors didn't relieve his symptoms. Subsequent high-resolution esophageal manometry made a diagnosis of hypercontractile esophagus. Treatment with vonoprazan resulted in symptomatic resolution and abnormal contractions were no longer detected on follow-up high-resolution manometry.
conclusionsPotassium-competitive acid blockers like vonoprazan offer an alternative therapeutic method for patients with hypercontractile esophagus who are refractory to proton pump inhibitor therapy. The use of potassium-competitive acid blockers in hypercontractile esophagus warrants further research and may provide evidence for an acid-related etiology of hypercontractile esophagus.
