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
Diabetic nephropathy (DN), a prevalent and severe complication of diabetes, is associated with poor prognosis and limited treatment options. N7-Methylguanosine (m7G) modification plays a crucial role in regulating RNA structure and function, linking it closely to metabolic disorders. However, despite its biological significance, the interplay between m7G methylation and immune status in DN remains largely unexplored. Leveraging data from the GEO database, we conducted consensus clustering of m7G regulators in DN patients to identify distinct molecular subtypes. To construct and validate m7G-related prognostic features and risk scores, we integrated multiple machine learning approaches, including Support Vector Machine-Recursive Feature Elimination, Random Forest, LASSO, Cox regression, and ROC curves analysis. In addition, we employed GSVA, ssGSEA, CIBERSORT, and Gene Set Enrichment Analysis to investigate the associated biological pathways and the immune landscape, providing deeper insights into the role of m7G methylation in DN. Based on the expression levels of 18 m7G-related regulatory factors, we identified nine key regulators. Through machine learning techniques, we identified four significant regulators (METTL1, CYFIP2, EIF3D, and NUDT4). Consensus clustering classified these genes into two distinct m7G-related clusters. To characterize these subtypes, we conducted immune infiltration analysis, differential expression analysis, and enrichment analysis, uncovering significant biological differences between the clusters. Additionally, we developed an m7G-related risk scoring model using the PCA algorithm. The differential expression of the four key regulators was further validated through in vivo experiments, reinforcing their potential role in disease progression. The m7G-related genes METTL1, CYFIP2, EIF3D, and NUDT4 may serve as potential diagnostic biomarkers for DN, providing new insights into its molecular mechanisms and immune landscape.
