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
Purpose: The aim of this study was to assess bowel wall thickness using B-mode ultrasound (US) and perfusion measurement by DCE-US in patients with a food allergy (FA) compared to healthy controls (HCs) and patients with active Crohn's disease (CD). Materials and Methods: Bowel wall thickness and perfusion were assessed in FA patients as well as in HCs on a potato rice diet (PRD) and after a provocation diet (PD). Additionally, patients with active CD were examined for further comparison. Results: A total of 48 individuals (20 with FAs, 20 with CD, and 8 HCs) were included. There was no significant difference between the HCs and patients with FAs regarding the thickness of the terminal ileum (1.8mm vs. 2.2mm; p=0.46) and the sigmoid colon (2.1mm vs. 2.1mm; p=1) on a PRD. After a PD, the median value was significantly lower in the terminal ileum for HCs compared to patients with FAs (1.6 mm vs. 2.3 mm; p=0.03). In CD patients, the thickness of the terminal ileum was far more pronounced (median thickness 6 mm) compared to HCs and patients with FAs (p<0.001). There was no statistically significant difference for all tested DCE-US parameters in the terminal ileum between the HCs and patients with FAs on either PRD or PD. However, DCE-US perfusion parameters (PE, WiAUC, WiR, WiPi, and WoR) were significantly higher in patients with CD compared to HCs and patients with FAs on a PD. Conclusion: Assessment of wall thickening of the terminal ileum using US and perfusion measurements via DCE-US appears to be insufficient for distinguishing between HCs and patients with FAs. However, US and DCE-US could be helpful in differentiating patients with CD from those with FAs.
