The Effect of Vitamin D3 Supplementation on Vitamin D Status and Associated Health Outcomes in Children: A Randomized Controlled Trial.
Trial report in The Journal of nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05018988 (The D-VinCHI Study), which is not on this 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.

Abstract
backgroundVitamin D is a key regulator of musculoskeletal growth, immune regulation, and cognitive function in children. As children in the United Kingdom (UK) and Ireland are at risk of vitamin D deficiency due to the northern latitude, supplementation is recommended. To our knowledge, the effect of supplementation on status and related health outcomes has not been investigated in children residing in the UK/Ireland.
objectivesTo examine the effect of vitamin D
methodsThe D vitamin in children study was a double-blind, randomized, placebo-controlled trial, conducted among healthy children (aged 4-11 y). Children received 12 wk of either 10 μg/d vitamin D
resultsOne hundred eighteen participants completed the study (mean age 8.1 ± 1.8 y; 51% girls). Supplementation significantly increased 25-hydroxyvitamin D concentration (from 66.31 ± 17.26 nmol/L to 69.04 ± 16.93 nmol/L) compared to a decline in the placebo group (63.67 ± 19.48 nmol/L to 56.29 ± 18.58 nmol/L; P < 0.001) and prevented deficiency during the extended winter months. No effects were observed on muscle function, cognitive function, immune function, or bone turnover markers.
conclusionsVitamin D insufficiency is prevalent in UK/Irish children, and supplementation in the form of an oral spray is effective in achieving/maintaining an adequate status in most children. Further research is warranted to elucidate mechanisms underpinning nonresponse to supplementation and to further investigate the potential beneficial effects of supplementation on cognitive function. This trial was registered at clinicaltrials.gov as NCT05018988.
