To evaluate the effect of simultaneous zinc and vitamin A supplementation on diarrhoea and acute lower respiratory infections in children.

Who Took Part

The abstract describes 800 children taking part.

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

How the Study Was Run

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

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.

Some children received a placebo instead of Vitamin D, K2, Magnesium and Zinc, giving a reference point.
