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
Metal ions are involved in many biological functions such as enzyme catalysis, signal transduction and gene expression regulation in biological system. They play multiple roles in the pathogenesis and immune escape mechanism of gastric cancer(GC). This review begins by outlining the fundamental biological roles of metal ions, highlighting its significance in tumor development. We focus on elucidating how metal ions modulate the gastric cancer immune landscape by regulating immune cell functions, and participating in specific signaling pathways. Additionally, the potential of metal ion interference as an emerging therapeutic strategy for tumors is discussed, along with the prospects for applying metal-based nanomaterials in the treatment of gastric cancer. Additionally, we discuss the crosstalk between ferroptosis and cuproptosis mediated by metal ions, which provides a novel perspective for understanding metal ion-dependent tumor cell death. The potential of metal ion interference as an emerging therapeutic strategy and the application prospects of metal-based nanomaterials in gastric cancer treatment are summarized. Finally, we point out key future research needs, including clarifying the dynamics of metal ions in the gastric cancer microenvironment, standardizing metal-related biomarkers for clinical stratification, and optimizing the safety and targeting of metal-based therapies. This review comprehensively summarizes the regulatory roles and mechanisms of metal ions in the gastric cancer immune microenvironment, offering theoretical support for the development of precision therapeutic strategies targeting metal ion homeostasis.
