Redox-Metabolic Crosstalk in Pediatric MASLD: Biomarkers, Mechanisms, and the Emerging Role of Selenium.
Review in International journal of molecular sciences, 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
Childhood obesity is an important global health issue closely related to metabolic syndrome and metabolic dysfunction-associated fatty liver disease (MASLD), currently the most common chronic liver disease in children. Oxidative stress and insulin resistance are the driving forces in hepatocyte injury and disease progression. There is growing interest in new biomarkers for detecting and monitoring metabolic and hepatic changes. We aimed to synthesize current evidence regarding biomarkers of oxidative stress and MASLD, and the potential modulatory role of selenium in pediatric populations. A literature search of PubMed, Scopus, Web of Science, and the Cochrane Library identified studies in children and adolescents (0-18 years) published between January 2000 and December 2025. Associative diagnostic biomarkers included indicators of oxidative damage, antioxidant-defense markers, and integrated oxidative stress indices, which appear promising but lack pediatric reference ranges, while prognostic biomarkers capture the inflammatory consequences of redox imbalance but with limited liver specificity. Metabolomics profiling and multiomics approaches remain experimental. Selenium, an essential trace element with antioxidant properties, plays a role in maintaining redox balance through selenoproteins, but pediatric evidence is limited and at times contradictory. Few biomarkers are clinically ready. Further longitudinal studies in pediatric populations are needed to better clarify the role of selenium, as well as to support the development of age-appropriate diagnostic strategies utilizing multiomics for MASLD, empowering clinicians to implement timely interventions in childhood obesity.
