Identification of hub genes associated with severe COPD via WGCNA and immune infiltration 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
Chronic Obstructive Pulmonary Disease (COPD) is a progressive respiratory disorder characterized by persistent inflammation and airflow limitation. This study aimed to investigate immune cell infiltration patterns and identify key hub genes associated with severe COPD using integrative bioinformatics analysis. We analyzed transcriptomic data from the GSE76925 dataset, comprising lung tissue samples from 111 individuals with severe COPD (GOLD stage 3-4) and 40 healthy controls. Bioinformatic approaches included weighted gene co-expression network analysis (WGCNA), immune cell infiltration estimation via CIBERSORT, random forest classification, hierarchical clustering, and correlation with clinical parameters such as FEV1 and FEV1/FVC ratios. Our analysis revealed distinct immune infiltration patterns and identified several hub genes significantly correlated with COPD severity. Notably, FEV1/FVC remained a robust clinical marker of disease progression. The hub genes SUMO1, HMGB1, and RBM39 were found to be strongly associated with immune-related pathways and disease severity. This study highlights the value of integrating immune infiltration analysis and gene co-expression networks to better understand the pathogenesis of severe COPD. The identification of key hub genes, including SUMO1, HMGB1, and RBM39, provides insights into potential biomarkers and therapeutic targets for this respiratory disease. Further validation using independent cohorts and functional experiments is warranted to confirm their clinical utility.
