Assessment of Esophageal Motor Disorders Using High-resolution Manometry in Esophageal Dysphagia With Normal Endoscopy.
Article in Journal of neurogastroenterology and motility, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
BACKGROUND/
aimsThe distribution and esophageal motor characteristics of Chinese patients with esophageal dysphagia who exhibit no structural abnormalities on esophagogastroduodenoscopy remain unclear. Our aim is to assess the esophageal motor patterns using high-resolution manometry (HRM) and classify them according to the Chicago classification version 3.0 (CC v3.0). Furthermore, we compared the CC v3.0 and the previous version 2.0 (CC v2.0) for diagnosis of motor disorders.
methodsTwo hundred thirty-six (mean age 48.4 ± 12.2 years, 61.9% female) patients with esophageal dysphagia were included for analysis of motor function using HRM. All participants were administered a questionnaire to determine Eckardt scores before HRM.
resultsAccording to the CC v3.0, 57 (24.2%) patients showed evidence of esophagogastric junction outflow obstruction and were classified as Group 1. Eighteen (7.6%) patients with major disorders of peristalsis were classified as Group 2. Minor disorders of peristalsis (Group 3) were much more frequent (129 [54.7%] patients). Thirty-two (13.6%) patients had normal esophageal manometry were classified as Group 4. All patients with abnormal pH or pH impedance monitoring (n = 44) had minor motor disorders (ineffective esophageal motility [IEM] = 34, fragmented peristalsis = 10). Based on motor category, the Eckardt score was 4.7 ± 0.1 in Group 1, 4.5 ± 0.3 in Group 2, 3.5 ± 0.1 in Group 3, and 3.9 ± 0.1 in Group 4.
conclusionsIEM was the most common esophageal motor disorder in patients with esophageal dysphagia who showed no structural abnormality on endoscopy. While a high Eckardt score suggests outflow obstruction or a major motor disorder, a low score suggests IEM.
