Non-invasive fluorescence sensing reveals changes in intestinal barrier function and gastric emptying rate in a first-in-human study of Crohn's disease.
Article in Therapeutic advances in gastroenterology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
Background: Crohn's disease is characterised by multifaceted changes in gut function, involving not just inflammatory effects but also alterations in gut barrier function and gastric motility. However, current diagnostic tools used to measure key gut functional parameters are invasive, unreliable or time-consuming. Thus, we applied a novel, non-invasive fluorescence sensing technology - transcutaneous fluorescence spectroscopy (TFS) - to investigate gut barrier function and gastric emptying in Crohn's disease. Objectives: Our study aimed to validate TFS for non-invasive gastrointestinal (GI) diagnostics and to explore changes in gut barrier function and gastric emptying rate simultaneously in Crohn's disease. Design: A cross-sectional study involving patients with Crohn's disease and healthy individuals. Methods: We performed fluorescent measurements and lactulose:mannitol (L:M) tests in 38 Crohn's disease patients and 20 healthy volunteers. We investigated multiple TFS-derived parameters as indicators of gut barrier function and gastric emptying rate. Using these parameters, we assessed differences between healthy volunteers, inactive Crohn's patients and active Crohn's patients, and calculated correlations between TFS and L:M values. Results: TFS-derived parameters revealed significantly increased intestinal permeability and delayed gastric emptying in patients with active Crohn's compared to healthy controls. TFS trends showed encouraging alignment with those from the L:M test, suggesting potential concordance with established methods. No adverse events were reported. Conclusion: TFS enables rapid, non-invasive discrimination of Crohn's patients from healthy volunteers and allows simultaneous assessment of gut barrier function and gastric emptying rate - two important aspects of GI function in Crohn's disease. This implies potential for improved monitoring and diagnosis of Crohn's disease (and other gut disorders) as well as more advanced study of gut function in health and disease.
