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
Hepatocellular carcinoma (HCC) is a major public health problem, with a poor prognosis in patients with advanced disease. We aimed to investigate the cytotoxic activity of coumestrol against human hepatocellular carcinoma HepG2 cells. Crystal violet (CV) assay was performed for cell cytotoxicity assessment on Vero cells (normal Kidney) and HepG2 cells. Apoptosis was analyzed by Annexin V/FITC staining. The relative expression of BAX, bcl-2, NF-Kβ, PCNA, MMP2, Caspase-3, Caspase-9, COX2, and MMP9 was detected using quantitative real-time PCR (qPCR). In addition, immunohistochemical analysis (IHC) of Bax, and PCNA were established. Results indicated that coumestrol induced significant toxicity in HepG2 cells. Annexin V-FITC staining assays revealed that coumestrol-induced cytotoxicity in HepG2 cells was mediated through apoptosis stimulation. The apoptosis in HepG2 cells was mediated through caspase-activation. Cell invasion was inhibited by coumestrol in HepG2 cells via inhibition of MMP-2 and MMP-9 expressions. IHC confirmed the strong expression of Bax and nuclear expression of PCNA in treated cells. To the best of our knowledge, limited studies have investigated the impact of coumestrol. The study showed that coumestrol exhibited cytotoxic and apoptotic effects against HepG2 cells, accompanied by inhibition of invasion-related gene expression.
