1 · What the graph read from it

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.

2 · The registry

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

Liver fibrosis is a dynamic process that occurs in response to chronic liver disease resulting from factors such as chronic infections, autoimmune reactions, allergic responses, toxins, radiation, and infectious agents. Among the infectious agents, multicellular parasites cause chronic inflammation and fibrosis. Twenty-five patients with different stages of cystic echinococcosis (CE) were enrolled in the study. The expression of ACTA2, COL3A1, IFN-γ, MMP2, MMP9, TGF-β1, and TNF-α genes was determined by qRT-PCR in healthy and fibrotic liver tissue of the CE patients. TGF-β1 expression was evaluated by immunohistochemistry, and histology was conducted to assess the development of liver fibrosis. Expression of MMP9, ACTA2, COL3A1, and MMP2 was found significantly higher in the fibrotic tissue compared to healthy tissue. We observed a significant correlation between TGF-β1 and TNF-α gene expressions and liver fibrosis. The mRNA level of IFN-γ was lower in the fibrotic than in the healthy hepatic tissue. Immunohistochemistry analysis revealed TGF-β1 upregulation in the fibrotic tissue. Histology showed inflammation and fibrosis to be significantly higher in the fibrotic tissue. The findings of this study suggest that Echinococcus granulosussensu lato can promotes fibrosis through the overexpression of TGF-β1, MMP9, ACTA2, COL3A1, and MMP2. The downregulation of IFN-γ mRNA in fibrotic samples is probably due to the increased production of TGF-β1 and the suppression of potential anti-fibrotic role of IFN-γ during advanced liver injury caused by E. granulosussensu lato.
