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
Objective: This study aimed to delineate the alterations in the gut microbiome and host amino acid metabolism in children with comorbid allergic rhinitis and functional constipation (ARFC), and to explore their links with clinical allergy markers. Methods: We performed shotgun metagenomic sequencing and amino acid-targeted metabolomics on fecal samples from 19 children with ARFC and 16 age-matched healthy controls (HC). Microbial community structure, differentially abundant taxa, and metabolic profiles were analyzed. Integrative analyzes, including correlation networks and machine learning modeling, were employed to investigate microbiota-metabolite-host interactions. Results: Significant beta-diversity distinction was found between ARFC and HC gut microbiota (PCoA R Conclusion: This multi-omics study unveils a distinct "gut dysbiosis-metabolite dysregulation-immune dysfunction" axis in ARFC children. The synergistic shift towards a mucolytic, pro-inflammatory microbiota alongside deficient immunomodulatory metabolite production, which correlates with clinical allergy markers, provides a novel mechanistic framework for this comorbidity and highlights potential diagnostic biomarkers for future validation.
