Effect of High-Dose vs Standard-Dose Vitamin D Supplementation in Pregnancy on Bone Mineralization in Offspring Until Age 6 Years: A Prespecified Secondary Analysis of a Double-Blinded, Randomized Clinical Trial.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in this randomized controlled trial publication.

Who Took Part

The study group was 584 children.

By PubMed's age tags, the people studied were infants, young children, children and adults, both men and women.

A prespecified analysis of a double-blinded, randomized clinical trial in the Copenhagen Prospective Studies on Asthma in Childhood 2010 mother-child cohort that included 623 pregnant mothers and their 584 children.

How the Study Was Run

In design terms this was a randomized and double-blind study.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

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

Data were analyzed between January 2019 and September 2019.

What Was Measured

PubMed files the paper under topics including Anthropometry, Bone Density, Denmark and Vitamin D.

What This Means in Plain Language
