A 2 × 3 multifactorial ANOVA with total responses per minute as dependent variable and strain and medication status as fixed factors showed significant effects of drug ( F (2,42) = 25.65, p < 0.001) and strain* drug interaction ( F (2,42) = 4.08, p = 0.024) with an effect of strain approaching significance ( F (1,42) = 4.04, p = 0.051).
