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
Background: Lung adenocarcinoma (LUAD) is the most common pathological type of lung cancer, and it has a high incidence and poor prognosis. Disulfidptosis is a novel form of death induced by disulfide stress caused by excessive intracellular cystine accumulation under glucose starvation conditions. This study investigated the significance of disulfidptosis-related long non-coding RNAs (DRlncRNAs) in the risk assessment and prognosis prediction of LUAD. Methods: RNA sequencing data and clinical information of LUAD patients were obtained from The Cancer Genome Atlas database. Differentially expressed genes associated with disulfidptosis were screened using univariate Cox regression analysis. A prognostic model was constructed using the least absolute shrinkage and selection operator and the Cox regression analysis to classify patients into high- and low-risk groups. Time-dependent receiver operating characteristic, C-index, and Kaplan-Meier curves were plotted and compared to evaluate the predictive ability of the prognostic model. Functional gene set enrichment analysis (GSEA) and single-sample GSEA were used to explore the characteristics of enrichment pathways, immune-related functions, and treatment response in the high- and low-risk groups. Results: A risk prognostic model was constructed consisting of eight DRlncRNAs ( Conclusions: The developed 8-lncRNA prognostic model serves as a valid biomarker for predicting LUAD prognosis and provides potential therapeutic insights. Targeting DRlncRNAs may contribute to improved prognosis and guide future therapeutic strategies.
