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
Background: Hepatocellular carcinoma (HCC) is one of the lethal malignancies with a poor prognosis due to metastatic complications. Matrix metalloproteinases (MMPs) and their inhibitors, tissue inhibitors of metalloproteinases (TIMPs), have an important role in metastasis. MicroRNA-21 (miR-21) is significantly overexpressed in nearly all types of human cancers, including HCC. Targeting miR-21 pharmacologically could be a promising therapeutic approach for HCC. 3,4-dihydroxyphenylethanol (DHPE), a phenolic phytochemical compound found in olive, has potent antioxidant and anticancer properties. This study aimed to investigate the effect of DHPE on the expression of miR-21 with genes associated with metastasis (MMP-2, MMP-9, TIMP-1, and TIMP-2) and their correlation with miR-21 in HepG2 cells. Methods: This experimental study had four groups, including a control, and three groups of treatment with different concentrations of DHPE (50, 100, and 150 µM) for 24 hours. The expression levels of genes were determined by RT-qPCR. Results: The results showed that the treatment of cells with DHPE significantly reduced the expression of miR-21, MMP-2, MMP-9, and TIMP-1 but increased TIMP-2 compared to the control group; additionally, there was a negative correlation between miR-21 and TIMP-2 but a positive correlation between miR-21 with MMP-2, MMP-9, and TIMP-1. Conclusions: The results showed that DHPE, likely by reducing the expression of miR-21, can increase TIMP-2 and reduce MMP-2, MMP-9, and TIMP-1 gene expression and may play a role in inhibiting cell migration in HepG2 cells.
