Role of Serum Magnesium Deficiency in Insulin Resistance Among Overweight and Obese Children: A Meta-Analysis.

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
Magnesium is an essential micronutrient that plays a critical role in insulin signaling, glucose metabolism, and energy balance. With the growing global burden of childhood obesity and metabolic dysfunction, serum magnesium deficiency has emerged as a potential modifiable factor in the development of insulin resistance. This meta-analysis aimed to evaluate the association between serum magnesium levels and insulin resistance among overweight and obese children. A comprehensive search of electronic databases and clinical trial registries was conducted for studies published between 2011 and 2025. Following rigorous screening and eligibility assessment, seven studies comprising a total of 960 children were included in the final analysis. Across the selected studies, serum magnesium deficiency was significantly associated with both obesity and insulin resistance. For obesity-related outcomes, the pooled odds ratio (OR) was 2.82 (95% CI: 1.99-3.95, p < 0.00001), with study-specific ORs ranging from 2.60 to 2.95. For insulin resistance, the pooled OR was 2.91 (95% CI: 2.10-4.04, p < 0.00001), with individual study ORs ranging from 2.60 to 3.25, all with p-values < 0.001. Heterogeneity across studies was low to moderate (I² = 32%, χ² = 8.82, df = 6, p = 0.18), indicating consistency in outcomes. These findings provide strong evidence that low serum magnesium levels are significantly associated with both obesity and insulin resistance in pediatric populations. Magnesium deficiency may act as both a biomarker and a contributing factor to early metabolic disturbances. Given its potential reversibility, early detection and dietary or supplemental correction of magnesium deficiency could be a valuable strategy in preventing or mitigating insulin resistance in overweight and obese children.
