Adherence to vitamin D supplementation guidelines in children under five years of age: a systematic literature review.
Synthesis in European journal of nutrition, 2024. 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
purposeDespite the presence of guidelines on vitamin D supplementation in infants and young children, little is known about parental adherence to their recommendations. This review aims to summarise the evidence from observational studies investigating adherence to vitamin D supplementation guidelines in children under five years of age.
methodsDatabases of PubMed, Scopus, Web of Science, and CINAHL were searched from January 2000 until July 2022. Qualitative data synthesis was used to summarise evidence on supplementation adherence. The adherence rate was categorised as low, moderate, and high if it was ≤ 50%, between 50 and 70%, and ≥ 70%, respectively.
resultsEleven studies investigating adherence to eight different vitamin D supplementation guidelines from European countries, USA and Canada were included. The majority of studies were cross-sectional and conducted among infants. Overall, the adherence rate ranged between 14.29% and 95.6%. Low, moderate, and high adherence to supplementation guidelines were reported in six, three, and two studies, respectively.
conclusionThere is generally poor adherence to vitamin D supplementation guidelines in children under five years of age. Nevertheless, the evidence comes from a limited number of studies, mainly conducted in infants, with high methodological heterogeneity in terms of the vitamin D supplementation guideline assessed and the definition of supplementation adherence in the study population. Further research is warranted to identify effective health promotion interventions to increase supplementation adherence and reduce the risk of vitamin D deficiency at this critical life stage.
