What This Study Did, in Plain Language

What Was Tested

This randomized controlled trial paper looks at Copper (Supplement).

The present study attempted to confirm this proposition in 3 ways: repeat the measures for 1 of the 2 copper enzymes (superoxide dismutase) in a new group of CF patients (males and females, N = 38), add another copper enzyme measure (plasma diamine oxidase) that has high sensitivity to copper status, and test if copper enzyme activities in CF patients rise by copper supplementation.

The last test was performed plus or minus zinc supplementation since poor zinc status may contribute to poor copper status.

Who Took Part

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

How the Study Was Run

In design terms this was a randomized and placebo-controlled study.

The participants were allocated by chance, so the Copper (Supplement) group and the comparison group should start out alike.

Some participants received a placebo instead of Copper (Supplement), giving a reference point.

Our Notes on the Compound

Copper (Supplement): The active site of cytochrome c oxidase is described as containing copper ions that are essential for electron transfer.
