Identification of Notch pathway-related biomarkers in patients with idiopathic pulmonary fibrosis.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The involvement of Notch pathway-related genes (NPRGs) in idiopathic pulmonary fibrosis (IPF) remains inadequately understood. This study identified novel NPRG-associated biomarkers in IPF through integrated analysis of the GSE28042 dataset and NPRG gene sets, with the goal of uncovering potential therapeutic targets. Initially, 7 overlapping candidate genes were identified by intersecting 1,361 differentially expressed genes (DEGs) between IPF and control samples, 4,883 key module genes associated with IPF, and 428 known NPRGs. Four biomarkers-IL4, PLXND1, NBEA, and GATA2-were prioritized using machine learning methods. Immune infiltration analysis, conducted with the CIBERSORT algorithm (v2.0.4), revealed that IL4, NBEA, and GATA2 were significantly positively correlated with resting dendritic cells and negatively correlated with follicular helper T cells. Additionally, drug target prediction and pathway enrichment analyses suggested potential associations between these biomarkers and oxidative stress-related pathways. RT-qPCR validation using human blood samples confirmed significant down-regulation of IL4 and NBEA while PLXND1 was significantly up-regulated in patients with IPF compared to healthy controls. These biomarkers may contribute to the pro-fibrotic microenvironment, and their dysregulation is linked to the pathogenesis of pulmonary fibrosis. In summary, the identified NPRG-related biomarkers hold diagnostic potential for IPF. with further research needed to clarify their functional roles and assess their viability as therapeutic targets or as consequences of the fibrotic process.
