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: We explored the effects of miR-133a-5p and ATP7B on cuproptosis in hepatocellular carcinoma. Methods: Initially, we assessed the impact of miR-133a-5p on hepatocellular carcinoma (HCC) using CCK-8 assays, cell scratch assays, and flow cytometry. Subsequently, we utilized elesclomol in combination with copper ions to induce cuproptosis in the HCC cell lines PLC/PRF/5 and Huh-7. We evaluated the influence of miR-133a-5p on cuproptosis using CCK-8 assays, cell scratch assays, flow cytometry, and Western blotting. To elucidate the underlying mechanisms, we employed bioinformatics to identify potential downstream target genes of miR-133a-5p and conducted dual-luciferase reporter assays to confirm the binding sites. Finally, we validated the regulatory effect of miR-133a-5p on ATP7B by modulating miR-133a-5p expression through cell transfection experiments. Results: The results from the CCK-8 assay, cell scratch assay, and flow cytometry demonstrated that miR-133a-5p significantly inhibits the proliferation and migration of HCC cells while promoting their apoptosis. Furthermore, Elesclomol in combination with copper ions induces cuproptosis in HCC cells. Compared to the cuproptosis observed in HCC as a control, miR-133a-5p further suppresses the proliferation and migration of HCC cells, enhances their death, and increases the expression of cuproptosis-related proteins more prominently. Bioinformatics analysis suggested that ATP7B might be a downstream target gene of miR-133a-5p. This was confirmed by dual luciferase assays, which identified a binding site between miR-133a-5p and ATP7B. Additionally, the expression levels of ATP7B were found to decrease or increase in response to the regulation by miR-133a-5p. Conclusion: MiR-133a-5p facilitates cuproptosis in hepatocellular carcinoma through targeting of ATP7B.
