Note: Subjective responses are continuous and standardized variables. GEE = generalized estimating equation; eBAC = estimated blood alcohol concentration; SE = standard error; CI = confidence interval; LL = lower limit; UL = upper limit; Average eBAC = average eBAC across all momentary drink reports during the monitoring period and reflects the between-person effect; Momentary eBAC = person-centered estimated eBAC and reflects the within-person effect;
