1 · What the graph read from it

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.

2 · The registry

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

Purpose: This study aimed to evaluate the diagnostic accuracy of gastric filling ultrasound, in combination with body mass index (BMI), for the dynamic assessment of gastroesophageal reflux in patients with gastroesophageal reflux disease (GERD)-like symptoms, using 24-h pH impedance monitoring and esophagogastroduodenoscopy (EGD) as reference standards. Methods: We enrolled 155 patients with GERD-like symptoms in our hospital. The results of gastric filling ultrasound, combined with BMI, were compared with 24-h pH impedance monitoring and EGD to assess GERD. Diagnostic accuracy was assessed using sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and Cohen's kappa statistics. A calibration curve was constructed to assess agreement between the model's predicted probabilities and the observed outcomes. Decision curve analysis (DCA) was performed to evaluate clinical utility. Results: GERD patients exhibited significant differences in terms of age, BMI, His angle, and all reflux-related metrics ( Conclusion: Gastric filling ultrasound is a dynamic imaging technique that visualizes GERD symptoms. The BMI-based gastric filling ultrasound, given its good correlation with 24-h pH impedance monitoring, is a promising auxiliary diagnostic tool for GERD.
