Dual facets of copper in the malignant transformation of oral submucous fibrosis: A narrative review.
Review in Molecular biology reports, 2026. 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
Copper is involved in the pathogenesis of oral submucous fibrosis (OSMF) and oral squamous cell carcinoma (OSCC). The exact role of copper in the malignant transformation of OSMF remains unclear. This review aimed to highlight the role of copper in OSMF and its transformation to OSCC. A literature review was conducted in databases such as PubMed and Google Scholar to identify and analyse studies relevant to copper metabolism in OSMF and OSCC. Copper increases lysyl oxidase activity, leading to increased collagen cross-linking and extracellular matrix deposition, characteristic of OSMF. Studies indicate that excess copper induces oxidative stress, leading to epithelial injury and a microenvironment that favors malignant transformation. Furhter more, moderate elevations in intracellular copper concentrations have been associated with increased cellular proliferation, metabolic activity, and angiogenesis in OSCC. Direct evidence for copper-driven malignant transformation in OSMF remains limited. Copper appears to act as a context-dependent regulator, promoting fibrosis and tumor progression at moderate concentrations and being cytotoxic at higher concentrations. Understanding these copper-mediated biological mechanisms can provide a foundation for developing biomarkers to predict malignant riskosition in OSMF patients and for designing therapeutic strategies that modulate copper homeostasis.
