Article in Journal of inflammation research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Purpose: This study aims to explore the effect and underlying mechanism of Chonggu Granules (CGG) in knee osteoarthritis (KOA) in rats. Methods: A papain-induced KOA model was established in rats. The pathological alterations of extracellular matrix in rat cartilage tissues were observed through hematoxylin and eosin (H&E) staining, followed by Mankin score for quantitative scoring. The ultrastructure of cartilage extracellular matrix was examined under a transmission electron microscopy (TEM). ELISA was used to measure the levels of IL-6, TNF-α, and IL-1β in rat serum. Immunofluorescence was performed for assessing the levels of MMP-3, MMP-13, and Col2al in rat cartilage. Western blot was used to identify the protein expressions of wnt1, GSK-3β, β-catenin, and Aggrecan in rat cartilage. The mRNA relative expressions of miR-148a-3p, wnt1, β-catenin, and GSK-3β in rat cartilage were detected by RT-PCR. Luciferase reporter gene was used to detect the target genes of miR-148a-3p. Results: CGG significantly improved articular cartilage tissue and extracellular matrix metabolism compared to the model group as indicated by H&E, Mankin score, and TEM data. Moreover, low, medium, and high doses of CGG reduced the levels of IL-6, TNF-α, IL-1β, MMP-3, and MMP-13 in serum to varying degrees but increased the levels of Col2al and Aggrecan. Mechanistically, CGG targeted wnt1 by increasing the expression of miR-148a-3p in a dose-dependent manner, thereby downregulating the mRNA and protein expressions of β-catenin in cartilage tissue and upregulating the mRNA and protein expressions of GSK-3β. Conclusion: CGG may control the miR-148a-3p/wnt/β-catenin signaling pathway to decrease the levels of its downstream target genes MMP-13 and MMP-3, increase the expressions of Col2al and Aggrecan, and downregulate the contents of inflammatory cytokines IL-6, TNF-α, and IL-1β, thereby improving the metabolism of cartilage extracellular matrix and alleviating the degeneration of articular cartilage in KOA.
