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
backgroundN6-methyladenosine (m6A) is the most abundant mRNA modification in mammals, participating in various biological processes. VIRMA is a key methyltransferase involved in m6A modification. However, the role of VIRMA in Hirschsprung's disease (HSCR) remains unclear. This study aims to investigate the function of VIRMA in HSCR and identify its corresponding regulatory mechanisms.
methodsThe expression of VIRMA and GSK3β in colon tissues of HSCR was examined using RT-qPCR, Western blot, and Immunohistochemistry. Immunofluorescence detected localization of VIRMA and GSK3β. Cell proliferation was measured by CCK8 and EdU assays, and cell migration was evaluated via cell migration and wound healing assays. The stability of GSK3β mRNA was assessed using the actinomycin D assay and the overall level of m6A in cells was assessed by colorimetric assay.
resultsVIRMA was significantly downregulated in narrow-segment colon tissue. Silencing of VIRMA inhibited cell proliferation and migration. VIRMA can inhibit the degradation of GSK3β mRNA and increase the expression of GSK3β. GSK3β was significantly upregulated in narrow-segment colon tissues. Accordingly, our findings showed that GSK3β mediated the VIRMA-driven cell migration and proliferation.
conclusionVIRMA can inhibit cell migration and proliferation by upregulating the expression of GSK3β, contributing to the onset of HSCR. IMPACT: The expressions of VIRMA were significantly reduced in HSCR, while GSK3β expression was increased in HSCR, and can be used as a molecular marker. VIRMA overexpression promoted the proliferation and migration of SH-SY5Y and HEK-293T cells. VIRMA can inhibit the degradation of GSK3β mRNA and increase the expression of GSK3β.
