Efficacy of oral vitamin D on glycated haemoglobin (HbA1c) in type 2 diabetics having vitamin D deficiency - 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.

Blood samples of both the groups were tested for glycated haemoglobin at three months to assess the change.

Who Took Part

The study group was 2 patients.

The age groups tagged for this paper are adults, middle-aged adults and older adults, both men and women.

This randomised control trial was carried out at Mayo Hospital, Lahore, from February 5 to August 5, 2016, and comprised type 2 diabetes patients aged 40-70 years visiting the outpatient clinics.

How the Study Was Run

The design is described as randomized.

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

They were randomly divided into two groups by using the lottery method.

Group A received oral vitamin D along with metformin and group B received metformin only.

SPSS 21 was used for data analysis.

What This Means in Plain Language

The paper is a randomized study of Vitamin D, K2, Magnesium and Zinc in 2 patients.

With fewer than 40 people, it is a small study, so it is better read as an early signal for further research than as a settled answer.

Its findings take up roughly 5 sentences of the abstract and are left out here on purpose; the source paper is the place to read them.
