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.
Who Took Part
PubMed indexes the participants as older adults, both men and women.
How the Study Was Run
In design terms this was a randomized, double-blind, placebo-controlled and multicenter 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.
As a double-blind Vitamin D, K2, Magnesium and Zinc study, the assignments were hidden from both participants and investigators until the end.
A placebo (an inactive look-alike) gave the Vitamin D, K2, Magnesium and Zinc group a baseline to be compared against.
Running at several centres spread the Vitamin D, K2, Magnesium and Zinc study over different clinics and patient groups.
The primary outcome was the change in AVC score.
Selected secondary outcomes included change in aortic valve area and peak aortic jet velocity on echocardiography, heart valve surgery, change in aortic and coronary artery calcification, and change in dp-ucMGP (dephosphorylated-undercarboxylated matrix Gla-protein).
What Was Measured
Topics PubMed links to this paper include Aortic Valve, Aortic Valve Stenosis, Calcinosis, Vitamin D and Vitamin K 2.
Author keywords: aortic valve calcification, coronary artery calcification, coronary artery disease, matrix Gla protein, randomized controlled trial and vitamin K2.
