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
backgroundWeaning stress-induced diarrhea is widely recognized as being associated with gut microbiota dysbiosis. However, it has been challenging to clarify which specific intestinal microbiota and their metabolites play a crucial role in the antidiarrhea process of weaned piglets.
resultsIn this study, we first observed that piglets with diarrhea exhibited a lower average daily gain and higher diarrhea score, and elevated levels of lipopolysaccharide (LPS) and D-lactate (D-LA) compared to healthy piglets. Subsequently, we analyzed the differences in intestinal microbial composition and metabolite levels between healthy and diarrheal weaned piglets. Diarrheal piglets demonstrated intestinal microbiota dysbiosis, characterized primarily by a higher Firmicutes to Bacteroidota ratio, a deficiency of Lactobacillus amylovorus and Lactobacillus reuteri, and an increased abundance of Bacteroides sp.HF-5287 and Bacteroides thetaiotaomicron. Functional profiling of the gut microbiota based on Kyoto Encyclopedia of Genes and Genomes (KEGG) data was performed, and the results showed that tryptophan metabolism was the most significantly inhibited pathway in piglets with diarrhea. Most tryptophan metabolites were detected at lower concentrations in diarrheal piglets than in healthy piglets. Furthermore, we explored the effects of dietary indole-3-aldehyde (IAld), a key tryptophan metabolite, on intestinal development and gut barrier function in weaned piglets. Supplementation with 100 mg/kg IAld in the diet increased the small intestine index and improved intestinal barrier function by promoting intestinal stem cell (ISC) expansion in piglets. The promotion of ISC expansion by IAld was also confirmed in porcine intestinal organoids.
conclusionsThese findings revealed that intestinal microbial tryptophan metabolite IAld alleviates impaired intestinal development by promoting ISC expansion in weaned piglets.
