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
Aim: This study aimed to determine the prevalence of esophageal hypomotility and examine its association with FSSG scores among Vietnamese patients presenting with reflux symptoms. Methods: A cross-sectional study was conducted in 403 adults with reflux-suspected symptoms and a GERD-Q score ≥ 8 undergoing high-resolution manometry (HRM) at Hoang Long Clinic (Hanoi, Vietnam). FSSG comprised two main components, including reflux score (FSSG-R) and dysmotility score (FSSG-M). Esophageal motility disorders were classified according to Chicago Classification v4.0; hypomotility disorders included ineffective esophageal motility (IEM) and absent contractility. Results: The mean FSSG total score and FSSG-M score were 15.91 ± 5.94 and 8.03 ± 3.84, respectively. On manometry, 66.0% of patients had a diagnosis of esophageal hypomotility, predominantly IEM (63.5%). Esophagogastric junction (EGJ) hypotension and EGJ morphology type III were seen in 15.38% and 3.47%, respectively. There were no significant differences on FSSG scores between patients with normal esophageal motility and hypomotility. Linear regression analysis showed no correlation between the FSSG-M score and distal contractile integral (DCI) or the number of ineffective swallows. In the multivariable logistic regression model, female and EGJ hypotension were significantly associated with the presence of esophageal hypomotility (aOR = 1.582 and 4.094, respectively). Conclusions: The prevalence of esophageal hypomotility among Vietnamese patients having reflux symptoms was high. FSSG total score and its dysmotility component score were not associated with the presence of esophageal hypomotility.
