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
This study aimed to evaluate the therapeutic properties of the traditional Chinese medicine Xuesanqi (XSQ, from the rhizome of Polygonum amplexicaule D. Don) in treating ulcerative colitis. We hypothesized that its many active components can alleviate symptoms of colitis by regulating the gut microbiota, its metabolites, and various signaling pathways. To test our hypotheses, we designed a DSS- induced colitis model in C57BL/6 male mice. Apparent metrics were evaluated in each group of mice and performed histological analysis of relevant tissues. The gut microbial composition was analyzed by 16S rRNA sequencing of bacteria. Simultaneously, the SCFAs content was detected by gas chromatography, inflammatory factor secretion was evaluated by ELISA or western-blot, the expression of tight junction protein and key proteins of the MAPK signaling pathway were analyzed by western-blot. Our result showed that the treatment with XSQ alleviated significant various symptoms such as weight loss, blood in stool, and shortening of colon. In addition, XSQ treatment restored the dysregulated gut microbiota in colitis mice, increased short chain fatty acids (SCFAs) and normalized the MAPK/ERK/JNK signaling pathways, promoted expression of tight junction protein Occludin, Claudin-1, and E-cadherin proteins. Furthermore, we also observed a dose-dependent pattern in these treatment responses. These findings demonstrated the active components of XSQ is a promising new treatment platform for ulcerative colitis.
