Bibliometrics and potential gene analysis of post-translational modifications in lung cancer.
Article in Journal of thoracic disease, 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
Background: Lung cancer is the most common cancer and the leading cause of cancer-related death. Post-translational modifications (PTMs) play a key role in tumor progression, but the functional mechanisms of many PTM-regulated genes remain unclear. In this study, we performed a bibliometric analysis to systematically evaluate the research trends of lung cancer PTMs worldwide. Methods: Data of Web of Science Core Collection (WOSCC) from 2000 to March 2025 were used to analyze the publication trends, collaboration networks, and keyword networks. Then, the functions of these genes were investigated by constructing protein-protein interaction (PPI) networks and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. Finally, unstudied genes were screened by constructing a differential gene set between the PTM database and genes retrieved from published articles. And their potential functions were explored by gene differential expression analysis, prognosis analysis, PTM pattern analysis, Gene Ontology (GO) analysis, and KEGG analysis. Results: China was the main contributor, followed by the United States and South Korea. Phosphorylation and methylation were the most studied PTMs, with STAT3 being the most reported gene. GO and KEGG analysis linked PTM-related genes to pathways such as cell cycle regulation. A total of 7,523 unstudied PTM-related genes in lung cancer were screened based on the PTM database. Differential expression and survival analysis revealed 134 candidate genes with potential functional relevance, mainly related to nuclear division and mitosis. Conclusions: This study highlights the growing interest in lung cancer PTM research and identifies a group of genes that have not been studied and may become novel therapeutic targets.
