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
backgroundIntestinal inflammation is a common and serious health problem in piglet production, especially enteritis caused by pathogenic Escherichia coli (E. coli). This condition often leads to high mortality, slow weight gain, and significant economic losses.
resultsIn this study, we isolated an E. coli strain, SKLAN202302, from the colon of diarrheal piglets to create an intestinal inflammation model for evaluating the protective effects of baicalin. Piglets infected with E. coli exhibited significant reductions in body weight, feed intake, small intestine length, and ileal goblet cell count (P < 0.05), along with deteriorated ileal morphology. However, baicalin supplementation resulted in body weights, feed intake, and intestinal morphology similar to those of the control group. Notably, there was a significant increase in the colonization of Lactobacillus species, particularly Lactobacillus_reuteri, Lactobacillus_amylovorus, and Lactobacillus_johnii, compared to the E. coli group (P < 0.05). At the metabolic and transcriptional levels, E. coli infection increased inflammatory mediators, including eicosanoids (leukotriene F4, prostaglandin F1a, leukotriene E4, thromboxane B2, prostaglandin G2, and PGH2), monosaccharides, and TCA cycle intermediates (oxoglutaric acid, glutaric acid, adipic acid, citric acid, and isocitric acid) in the ileum. It also promoted the expression of genes related to autoimmune diseases and the Th17 differentiation signaling pathway (CTLA4, IFN-ALPHA-8, IL12RB2, TRAV3, TRAV16, FOS, and VEGFA), as well as inflammatory factors. Conversely, baicalin supplementation not only counteracted these effects but also enhanced the presence of metabolites such as phospholipids [including lysoPC (P-18:1(9Z)/0:0), PC (17:0/0:0), lysoPC (16:1(9Z)/0:0), PC (18:0/0:0), lysoPC (18:0/0:0), PA (10:0/i-16:0), and PA (10:0/8:0)] and amino acids. It also regulated genes within the IL-17 signaling pathway (IL4, CCL17, CXCL10, IFNG, and CXCL2), suggesting a mechanism by which baicalin mitigates E. coli-induced intestinal and microbial disturbances. Subsequent flow cytometry analysis showed that E. coli infection increased the numbers of CD3
conclusionsBaicalin supplementation effectively alleviates E. coli-induced intestinal inflammation and microbial disturbances in piglets by enhancing beneficial Lactobacillus colonization, counteracting inflammatory mediators, and regulating immune-related gene expression and the Th17/Treg balance. These findings highlight baicalin's potential in alleviating intestinal inflammation.
