Effect of monthly vitamin D on diverticular disease hospitalization: Post-hoc analysis of a randomized controlled trial.

What Was Tested

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

Some studies have linked low vitamin D status and high risk of diverticular disease, but the causal relationship between vitamin D and diverticular disease remains unclear; clinical trial data are warranted.

Who Took Part

According to the abstract, 5108 participants were involved.

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

How the Study Was Run

In design terms this was a randomized, double-blind and placebo-controlled 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 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.

What Was Measured

The subject headings attached to it are Dietary Supplements, Diverticular Diseases, Hospitalization, Vitamin D and Vitamins.
