Construction and validation of immune prognosis model for lung adenocarcinoma based on machine learning.

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
Introduction: Lung adenocarcinoma is a leading subtype of lung cancer with high rates of recurrence and metastasis. Identifying novel prognostic biomarkers is essential for improving patient outcomes. Methods: Transcriptomic and clinicopathological data from TCGA (55 tumor samples and 38 normal samples) were used to construct a prognostic model, with 30 samples for internal validation. An external validation cohort (10 tumor-normal pairs) was obtained from the First Affiliated Hospital of Wenzhou Medical University. Differentially expressed genes and immune-related genes from the IMMPORT database were integrated using WGCNA. Three machine learning algorithms-Random Forest, LASSO, and SVM-RFE-were applied to identify key hub genes. A multivariate Cox regression model was built to predict survival. Model performance was assessed by time-dependent ROC and ANN models. Immune infiltration was analyzed using TIMER and ssGSEA, with consensus clustering performed to explore immune subtypes. Protein expression and biological functions of hub genes were validated using the HPA database and GSEA. Results: A total of 1,822 DEGs were identified, with 68 immune-related genes significantly associated with LUAD prognosis. Four hub genes-CBLC, GDF10, LTBP4, and FABP4-were selected to construct the prognostic model, which showed strong predictive performance in both ROC and ANN analyses. Immune profiling revealed elevated CD4⁺ T cells, macrophages, and dendritic cells in LUAD. Consensus clustering identified two immune subtypes with distinct prognoses and immune landscapes. Discussion: This study established a robust immune-related prognostic model for LUAD and identified key biomarkers associated with immune infiltration and survival. These findings offer valuable insights for personalized diagnosis and treatment strategies in LUAD.
