The interaction of naltrexone with OPRM1 genotype on the amount of drinks consumed after the priming drink in the bar-lab (table 2) was also not significant (F(1,79)=1.20, p=.28). There was also no main effect of OPRM1 genotype (F(1,81)=0.01, p=.99) or medication (F(1,81)=.01, p=.99) on the amount of drinks consumed in the bar lab.
