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
backgroundScutellaria baicalensis Georgi, a traditional Chinese herb, is known for its various biological effects, including antibacterial, anti-inflammatory, antioxidative, and antitumor properties. However, the function and mechanisms of methanol extract of Scutellaria baicalensis Georgi (MESB) in treating hepatic fibrosis remain unclear.
methodsThis study utilized a CCl4-induced mouse model of hepatic fibrosis to assess the effects of MESB through histopathological analysis and serum tests. The anti-fibrosis mechanism of MESB was investigated using qPCR, Western blotting, RNA interference, proteomics, and metabolomics. Spatial metabolomics identified key components of MESB in liver tissue, while molecular docking determined their targets.
resultsTreatment with MESB alleviated hepatic pathological changes and reversed hepatic fibrosis in the CCl4-induced models, as evidenced by decreased collagen fibers deposition, reduced expression of hepatic fibrosis markers COL1A1, FN, and PAI-1, and lowered serum levels of AST and ALT. In vitro, MESB inhibited the proliferation of LX-2 cells and the expression of hepatic fibrosis markers. Furthermore, MESB intervention modulated various pathways, particularly those involved in metabolic pathways. Subsequent metabolomics analysis demonstrated that MESB disrupted glycerophospholipid metabolism and suppressed arachidonic acid metabolism. MESB downregulated the expression of cPLA2 in LX-2 cells, leading to decreased production of arachidonic acid and its downstream inflammatory mediators. Meanwhile, MESB inhibited the expression of cPLA2 and its downstream NF-κB pathway in the liver tissues of models induced by CCl4. Additionally, silencing cPLA2 markedly reduced the expressions of COL1A1, FN, and PAI-1. Spatial metabolomics analysis confirmed the penetration of baicalein, wogonin and wogonoside into liver tissue. Further results indicated that baicalein and wogonin inhibited the expression of cPLA2, while baicalin and wogonoside do not exhibit this effect. Moreover, molecular docking suggested that baicalein and wogonin possess the potential to directly interact with cPLA2.
conclusionThis study reveals that MESB is crucial in preventing hepatic fibrosis via the cPLA2-mediated arachidonic acid metabolic pathway, highlighting its key active components as potential drugs for fibrosis treatment.
