Identifying risk factors for vomiting during diarrhea: A secondary analysis of a randomized trial of zinc supplementation.

What Was Tested

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

Who Took Part

The abstract describes 4500 children taking part.

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

The researchers performed a secondary data analysis of 4500 children aged 6-59 months with an acute episode of diarrhea (<72 h before enrollment) in a randomized, double-blind controlled trial in India and Tanzania.

How the Study Was Run

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

The children were allocated by chance, so the Vitamin D, K2, Magnesium and Zinc group and the comparison group should start out alike.

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.

What Was Measured

PubMed files the paper under topics including Acute Disease, Dehydration, Diarrhea, Dietary Supplements, India, Risk Factors and Tanzania.

Author keywords: children.

What This Means in Plain Language

Its findings take up roughly 6 sentences of the abstract and are left out here on purpose; the source paper is the place to read them.
