Effect of vitamin D supplementation on serum vitamin D levels and health outcomes in pediatric population with obesity/overweight: a systematic review and meta-analysis.
Synthesis in International journal of obesity (2005), 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
backgroundBecause 25-hydroxy cholecalciferol is lipophilic, children with obesity/overweight are at increased risk of its deficiency, potentially leading to health issues such as compromising bone mineralization and cardiometabolic health.
objectivesOur goal was to assess the impact of 25-hydroxy cholecalciferol supplementation on serum Vitamin D levels and various health parameters such as BMI and cardiovascular risk markers. METHODOLOGY: Data were extracted from PubMed, Embase, and Google Scholar. Following search string was used in each database: (Vitamin D OR 25(OH)D OR cholecalciferol) AND (Obese OR Overweight) AND (randomized trial OR RCT OR intervention) AND (children OR adolescent OR pediatric). Clinical trials assessing the impact of 25-hydroxy cholecalciferol D supplementation in pediatric populations with overweight or obesity, regardless of formulation, dosage, or duration, were included. A total of 24 studies were included in the systematic review, of which 11 randomized controlled trials were eligible for meta-analysis. The included studies' quality was evaluated using the Cochrane Risk of Bias (ROB-2) tool. Primary outcome was serum Vitamin D levels while secondary outcomes include cardiovascular risk markers, lipid profile, insulin sensitivity, and change in BMI. Follow-up done at 8 weeks, 12 weeks, 24 weeks, 26 weeks, 3 months, 6 months, and 12 months.
resultsSupplementing with 25-hydroxy cholecalciferol significantly raised the levels of serum vitamin D in children with obesity/overweight. No adverse events occurred following supplementation. Decrease in BMI, serum triglycerides and inflammatory markers were observed but its effects on metabolism and cardiovascular health remained insignificant. According to meta-analysis, vitamin D supplementation (interventional) arm group differed from the placebo by a standardized mean difference of 3.12 ng/ml (95% CI:1.72-4.52).
conclusionVitamin D supplementation in children with overweight /obesity correct the deficiency and significantly raise Vitamin D levels with no adverse events. To assess effective therapies to enhance metabolic and cardiovascular outcomes in the pediatric population with overweight/obesity, new trials should be conducted.
