What This Study Did, in Plain Language
What Was Tested
This randomized controlled trial looks at Therapeutic nicotine (patch, non-peptide).
As individual difference in response to nicotine may be related to a functional polymorphism in the gene encoding catechol-O-methyltransferase (COMT), an enzyme that strongly influences cortical dopamine metabolism, this study examined the modulatory effects of the COMT Val158Met polymorphism on the neural response to acute nicotine as measured with resting-state electroencephalographic (EEG) oscillations.
Who Took Part
The age groups tagged for this paper are young adults and adults, men only.
How the Study Was Run
The researchers set it up as a randomized, double-blind and placebo-controlled study.
The participants were allocated by chance, so the Therapeutic nicotine (patch, non-peptide) group and the comparison group should start out alike.
As a double-blind Therapeutic nicotine (patch, non-peptide) study, the assignments were hidden from both participants and investigators until the end.
Some participants received a placebo instead of Therapeutic nicotine (patch, non-peptide), giving a reference point.
