Vitamin D supplementation: are multivitamins sufficient?
Article in Archives of disease in childhood, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundPublic Health England advises 400 IU/day vitamin D supplementation for children over 1 year. Commercially available children's multivitamin and vitamin D supplements were surveyed to determine the vitamin D content.
methodsMultivitamins and vitamin D supplements marketed at children <12 years and sold by nine UK supermarkets and health supplement retailers were surveyed. Vitamin D content was determined from manufacturer's websites and product packaging.
results67 multivitamins were surveyed, containing 0-800 IU/day vitamin D. Only 25%-36%, depending on the child's age, provided ≥400 IU/day vitamin D. Supplements containing only vitamin D or labelled as for 'healthy bones' typically had higher vitamin D content (57%-67% contained ≥400 IU/day).
conclusionsFew multivitamin products supply the recommended 400 IU/day vitamin D. Clinicians need to be aware of this when recommending vitamin D supplementation and advise parents/carers to choose a product that contains ≥400 IU/day vitamin D.
