(B) “Beer before wine and you'll feel fine; wine before beer and you'll feel queer?”—comparison of intraindividual differences of AHS ratings, according to the order in which beer and wine were consumed, depicted for the 2 study groups. Data are presented as medians and quartiles using Tukey box plots; to compare intraindividual differences of AHS ratings (B) Welch's two-sample t-test was used at a 5% significance level.
