Hypercontractile Esophagus: An Underrecognized Cause of Dysphagia with a "Nutcracker" Appearance on Barium Esophagram.
Article in Journal of Brown hospital medicine, 2026. 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
Esophageal motility disorders are an important and uncommon cause of dysphagia when structural abnormalities are absent. We present a case of a 77-year-old woman with dysphagia and regurgitation whose barium esophagram demonstrated a characteristic "nutcracker" appearance of the distal esophagus. Despite this striking radiographic finding, peristalsis was preserved, and a barium tablet traversed the segment without obstruction. These features argue against classic diffuse esophageal spasm and instead suggest a hypercontractile motility disorder. This case highlights the role of barium esophagram as a complementary diagnostic tool while emphasizing that definitive classification of esophageal motility disorders requires high-resolution manometry.
