Hypermethylation of Ring finger protein 41 promoter is associated with early hepatitis B virus-related cirrhosis.

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
Objectives: New biomarkers are needed to detect liver cirrhosis at an earlier stage and to individualize treatment strategies. This study specifically investigates the diagnostic potential of Ring finger protein 41 promoter methylation as an epigenetic biomarker for detecting early-stage hepatitis B virus-related liver cirrhosis. Methods: The methylation level of the Ring finger protein 41 promoter in peripheral blood mononuclear cells of 190 participants were quantified with Methylight, and the changes of serum inflammatory cytokines related to liver fibrosis were analyzed simultaneously. Results: Patients with early-stage liver cirrhosis exhibited significantly higher methylation levels of Ring finger protein 41 promoter than chronic hepatitis B patients and health controls, accompanied by reduced mRNA expression. Remarkably, the receiver operating characteristic analysis demonstrated that Ring finger protein 41 promoter methylation achieved a superior diagnostic performance (area under the curve) for distinguishing hepatitis B virus-related compensated liver cirrhosis, outperforming conventional non-invasive indicators including liver stiffness measurement, aspartate aminotransferase-to-platelet ratio index, and fibrosis-4 score. Conclusion: Ring finger protein 41 may play a critical role in the pathogenesis of liver cirrhosis, with its methylation status in peripheral blood mononuclear cells demonstrating strong potential as a non-invasive biomarker for early liver cirrhosis detection.
