Neutrophil Extracellular Trap-Related Gene Signatures and Molecular Clusters in Severe Influenza: Identification Through Integrative Transcriptome Analysis.

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
backgroundNeutrophil extracellular traps (NETs) are recently discovered structures in which neutrophils trap pathogens in web-like structures composed of chromatin and proteolytic material. NETs have been linked to tissue damage in severe influenza (sFlu) pathogenesis. The present article involved a thorough analysis of NET-related gene (NRG) expression patterns and immunological characteristics in sFlu.
methodsMicroarray datasets were downloaded from the GEO database. sFlu-related NRGs (sFlu-NRGs) were screened using differential expression analysis and weighted gene co-expression network analysis (WGCNA). Hub sFlu-NRGs were identified using LASSO regression, support vector machine (SVM), and random forest (RF) models. Hub genes were subsequently validated using an additional external dataset, clinical samples, and a nomogram model. The molecular clusters in sFlu were investigated based on the hub sFlu-NRGs using consensus clustering and related immune cell infiltration.
resultsA total of 13 sFlu-NRGs were identified. Using these 13 genes, five (PRTN3, MMP8, myeloperoxidase [MPO], bactericidal permeability-increasing [BPI], and LTF) hub sFlu-NRGs were identified using three machine learning algorithms. Nomogram calibration and receiver operating characteristic (ROC) analysis results suggested that accuracy was achieved in predicting sFlu. Two molecular clusters were defined in sFlu based on the five hub genes. Single-set gene expression analyses suggested that, compared with Cluster 2, Cluster 1 had a decreased adaptive immune response.
conclusionsFive hub NRGs and two distinct NET-related clusters were identified in sFlu patients, highlighting the mechanism of action of sFlu and identifying candidate anti-sFlu therapeutic targets.
