Prognostic significance of genes associated with disulfidptosis in lung squamous cell carcinoma.

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
backgroundThis study aimed to investigate the relationship between disulfidptosis-related genes (DRGs) and lung squamous cell carcinoma (LUSC).
methodsUsing the TCGA-LUSC dataset, WGCNA identified LUSC-related genes, and hub genes were obtained after intersecting these with DRGs. Consensus clustering analysis divided LUSC patients into different subtypes and differentially expressed genes were then identified. LASSO-Cox regression was applied to establish a prognostic model, followed by analyses of immune cell infiltration and drug sensitivity. Finally, in vitro experiments confirmed the results of bioinformatics analysis.
resultsAfter intersecting 9,157 LUSC-related genes with 24 DRGs, 12 hub genes were identified. Two subtypes (Cluster 1 and Cluster 2) for LUSC were recognized, and 219 differentially expressed genes were screened. A prognostic model was constructed based on 7 genes (CD300LG, PCDHGA12, HPD, KANK4, PPBP, ZCCHC5, and CSMD3), with good predictive ability. Neutrophils, plasma cells, T cells CD4 memory resting, and T cells follicular helper displayed significant differences between different risk groups and subtypes. ZCCHC5 and PCDHGA12 were negatively correlated with all 20 screened drugs. In vitro experiments confirmed the occurrence of disulfidptosis and the levels of prognostic genes in LUSC.
conclusionThe study identified two LUSC subtypes and established a 7-gene prognostic model based on DRGs, which can be used as a new prognostic tool for LUSC.
