Discovery of Multiple Effects of Reactive Oxygen Species on Lung Adenocarcinoma at the Single-cell and Bulk Tissue Levels.
Article in Current medicinal chemistry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundReactive oxygen species (ROS) are potential targets for treating malignant tumors.
aimsThe aim of this study was to probe into the mechanisms of disease development and treatment in lung adenocarcinoma (LUAD).
objectiveThis study investigated the impact of ROS on the progression of LUAD at different transcriptomic levels and analyzed key molecules involved in the regulation of LUAD.
methodsSingle-cell RNA-seq (scRNA-seq) data of LUAD were clustered and annotated to determine cell types. Scissor cells based on LUAD bulk transcriptome and epithelial scRNA-seq data were used to classify subsets associated with ROS phenotypes. Least absolute shrinkage and selection operator (LASSO) and stepwise multivariate regression analyses were performed between the Scissor-positive and Scissor-negative epithelial cells to select key differentially expressed genes (DEGs) for developing a ROS-related signature.
resultsThe ROS score was significantly negatively correlated with the overall survival (OS) of LUAD. Seven cell types from the LUAD tissues were identified. The ROS-related gene signature was significantly correlated with metabolism, tumor microenvironment (TME) indicators, and the half-maximal inhibitory concentration (IC
conclusionThe current study provided novel insights into the impact of ROS on LUAD pathology at both single-cell and bulk-tissue levels, facilitating the prognostic evaluation and drug therapy development for patients with LUAD.
