Reproducibility in patterns of IGF generation with special reference to idiopathic short stature.

What Was Tested

Researchers studied Human Growth Hormone in this randomized controlled trial publication.

Insulin-like growth factor I (IGF-I) and insulin-like growth factor binding protein 3 (IGFBP-3) generation tests are both sensitive and specific measures of growth hormone (GH) sensitivity.

Recently, the question of reproducibility of IGF generation tests has been raised.

Who Took Part

According to the abstract, 3 patients were involved.

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

How the Study Was Run

The researchers set it up as a randomized study.

Random assignment meant chance, not the researchers, decided who got Human Growth Hormone and who got the comparison, which limits bias.

Samples were collected at baseline and on days 5 and 8 of GH administration.

What Was Measured

Topics PubMed links to this paper include Growth Disorders, Human Growth Hormone, Insulin-Like Growth Factor Binding Protein 3, Insulin-Like Growth Factor I, Recombinant Proteins, Regression Analysis and Reproducibility of Results.

What This Means in Plain Language

The paper is a randomized study of Human Growth Hormone in 3 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 4 sentences of the abstract and are left out here on purpose; the source paper is the place to read them.

The publication is from 2003 (Hormone research), a journal based in Switzerland.
