Machine learning identifies neutrophil-related signatures for diagnostic value in neonatal sepsis.

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
Neonatal sepsis (NS) is one of the leading causes of neonatal mortality. The nonspecific clinical manifestations and the limited timeliness of existing biomarkers (such as C-reactive protein) highlight the urgent need for highly accurate diagnostic tools. Neutrophils, as key effector cells of innate immunity, are closely involved in the progression of NS. This study integrated training (GSE69686) and validation (GSE25504) datasets from the GEO database. Neutrophil infiltration characteristics were analyzed utilizing CIBERSORT, and weighted gene co-expression network analysis (WGCNA) was introduced to determine neutrophil-related co-expression modules. Three machine learning algorithms-LASSO, SVM-RFE, and RF-were implemented to cross-screen core diagnostic genes. A combined diagnostic model was distributed based on these genes. NetworkAnalyst was utilized to predict miRNA-TF regulatory networks, and GSVA was conducted to interpret biological functions. Three algorithms identified IL1R2 and METTL7B as core diagnostic genes; the model showed strong reliability. IL1R2 high expression correlated with reduced CD8
