Effects of therapeutic zinc supplementation for diarrhea and two preventive zinc supplementation regimens on the incidence and duration of diarrhea and acute respiratory tract infections in rural Laotian children: 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.

This individually randomized, double-blind placebo-controlled trial was designed to evaluate the effects of different zinc supplementation regimens on the incidence and duration of diarrhea and acute lower (ALRI) and upper (AURI) respiratory tract infections among rural Laotian children.

Why It Was Studied

Diarrhea and respiratory tract infections are leading causes of childhood morbidity and mortality.

The study included 3407 children, 6-23 months at enrollment.

Who Took Part

According to the abstract, 3407 children were involved.

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

How the Study Was Run

The researchers set it up as a randomized, double-blind and placebo-controlled study.

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

Neither the children nor the staff measuring them knew who was on Vitamin D, K2, Magnesium and Zinc, so expectations could not easily colour the readings.

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

What Was Measured

The subject headings attached to it are Diarrhea, Dietary Supplements, Incidence, Laos, Respiratory Tract Infections, Rural Population and Zinc.

What This Means in Plain Language

The paper is a randomized, double-blind and placebo-controlled study of Vitamin D, K2, Magnesium and Zinc in 3407 children.

With several hundred people or more, it is a fairly large study for this kind of research.

Results are reported in around 9 sentences of the abstract; we leave them to the paper itself rather than summarise them.
