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: To address the core pathological features of intestinal barrier disruption and immune imbalance in ulcerative colitis (UC), we developed a nano-targeted formulation (GGQL nano-preparation) based on berberine, puerarin, baicalin, and glycyrrhizin by combining traditional Chinese medicine (TCM) and nanotechnology in this study. We aimed to investigate whether GGQL nano-preparation could promote M2 macrophage polarization, correct intestinal inflammation, and treat UC. Methods: We used databases to identify M2 macrophage-related gene targets for GGQL nano-preparation in UC. Protein-protein interaction networks, topological analysis, and GO/KEGG enrichment analyses revealed GGQL nano-preparation's potential regulation of macrophage polarization via a specific pathway. We validated this using a dextran sulfate sodium (DSS)-induced UC model in C57BL/6 mice. Parameters assessed included the disease activity index (DAI), colon length, colitis macroscopic damage index (CMDI), spleen index, and pathological changes (via HE staining). Immunohistochemistry detected AMPK-PPAR axis factor changes to determine GGQL nano-preparation's impact on M2 macrophage polarization and intestinal inflammation. Results: Our analyses suggested the GGQL nano-preparation reduced the DAI, enhanced colon length, improved CMDI scores, and mitigated splenic inflammation. HE staining showed GGQL nano-preparation alleviated inflammation in the spleen, lungs, and colon. Immunohistochemical findings indicated GGQL nano-preparation upregulated AMPK, PPAR, and SIRT1 expression. Mechanistically, GGQL nano-preparation promoted M2 macrophage polarization through the AMPK-PPARγ axis, achieving therapeutic objectives for UC. Conclusion: The GGQL nano-preparation effectively promotes M2 macrophage polarization via the AMPK-PPARγ axis, treating UC.
