What This Study Did, in Plain Language

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as a randomized controlled trial.

US National Institutes of Health.

Who Took Part

The age groups tagged for this paper are children and teenagers, both men and women.

Participants, care providers, and all trial staff were masked to group assignment during the intervention.

The fracture and safety analyses included participants who completed at least one follow-up fracture questionnaire.

How the Study Was Run

The design is described as randomized, double-blind, placebo-controlled and multicenter.

Random assignment meant chance, not the researchers, decided who got Vitamin D, K2, Magnesium and Zinc and who got the comparison, which limits bias.

Blinding on both sides kept the participants and researchers unaware of who received Vitamin D, K2, Magnesium and Zinc.

The comparison arm used a placebo, so changes seen with Vitamin D, K2, Magnesium and Zinc could be set against what happens without it.

More than one site took part, so the participants came from several places.

The researchers did a multicentre, double-blind, randomised, placebo-controlled trial across 18 public schools in Ulaanbaatar, Mongolia.

Prespecified secondary outcomes were incidence of fractures and adverse events, ascertained using questionnaires.

The trial is registered with ClinicalTrials.gov, NCT02276755, and the intervention ended in May, 2019.
