Note: BrAC
100 = breath alcohol concentration multiplied by 100 to aid in model convergence; AUQ = alcohol urge questionnaire; STIM = biphasic alcohol effects scale stimulation; SED = biphasic alcohol effects scale sedation; HA-POS = subjective effects of alcohol scale high arousal positive affect; LA-POS = subjective effects of alcohol scale low arousal positive affect; S = random slope, subscript indicates change over time or provides the pairwise comparison for predicting slope from condition (e.g., S30-P = dummy coded condition predicting the random slope capturing change over time in the outcome for that section of the table); SD = standard deviation; CI = credibility interval.
indicates an estimate that was significant based on the p-value but not based on the Bayesian CI. All results are from the model with placebo as the referent group besides effects that compare 30mg to 200mg, which came from the re-run of the model for all pairwise comparisons.
