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
Introduction: Pyroptosis is a distinctive form of inflammatory cell death, mediated by the activation of the inflammasome, which initiates a potent inflammatory response. Long non-coding RNAs (lncRNAs) modulate pyroptosis by targeting microRNAs and their target genes through a competing endogenous RNA (ceRNA) mechanism. Our previous research has confirmed that Polysaccharide of Atractylodes macrocephala Koidz (PAMK) can alleviate inflammatory liver injury in mice caused by lipopolysaccharide (LPS), but the specific molecular mechanism remains unclear. Additionally, recent studies have identified recruited macrophages in the liver as a key component of both acute and chronic liver inflammation. This study aimed to explore the impact of PAMK on LPS-induced macrophage pyroptosis and its molecular mechanism in mitigating inflammatory liver injury in mice. Methods: C57BL/6 mice were subjected to LPS-induced liver injury with or without PAMK pretreatment. Histopathological analysis, qRT-PCR, Western blot, and ELISA were performed to assess liver damage and pyroptosis markers. In RAW264.7 macrophages, dual-luciferase assays validated ceRNA interactions, while gain/loss-of-function experiments elucidated molecular mechanisms. Results: In this study, we found that PAMK alleviated LPS-induced inflammatory liver injury in mice and modulates macrophage pyroptosis through the lncRNA GAS5/miR-223/NLRP3 axis. Conclusion: We conclude that there is a ceRNA relationship between GAS5, miR-223-3p, and NLRP3; PAMK alleviates LPS-induced pyroptosis in macrophages through the lncRNA GAS5/miR-223-3p/NLRP3 axis; and PAMK intervention in the macrophage pyroptosis process subsequently alleviates liver inflammation.
