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
Objective: Cardiac aging is a major risk factor for the development of cardiovascular diseases. Although evidence suggests an association between N6-methyladenosine (m6A) modification and numerous cardiovascular diseases, its role in cardiac aging remains unclear. This study was conducted to elucidate the role of m6A modification in cardiac aging and the molecular mechanisms involved. Methods: Global methylation levels and the expression of major m6A regulators were compared between young and aged hearts. Transcriptome-wide m6A landscape analysis was conducted using methylated RNA immunoprecipitation sequencing (MeRIP-seq) and RNA sequencing (RNA-seq) to identify aberrant m6A peaks. Furthermore, gene set enrichment analysis (GSEA) was performed to identify gene sets associated with cardiac aging. Functional validation of key molecules was carried out through Results: The overall m6A level remained constant; however, the expression of the methyltransferase METTL14 and the demethyltransferase FTO were significantly upregulated in aged hearts. Knockdown of METTL14 alleviated H Conclusion: Our findings indicate that m6A modification plays an essential role in the process of cardiac aging. EFEMP1 may serve as a potential new therapeutic target for age-related cardiac diseases.
