Values are presented as median (Q1, Q3) or numbers (%). PONV: postoperative nausea and vomiting, BMI: body mass index, ASA: American Society of Anesthesiologists, 5-HT3R: 5-hydroxytryptamine receptor. *Categorical variables were compared by the chi-square test. Continuous variables were compared by the Mann-Whitney U test. †During the first 24 h postoperatively.
PONV: postoperative nausea and vomiting, OR: odds ratio, BMI: body mass index, ASA: American Society of Anesthesiologists, 5-HT3R: 5-hydroxytryptamine receptor. *A univariable binary logistic regression analysis was performed for each variable, respectively. †A multivariable binary logistic analysis with backward stepwise conditional method including the variables with statistical significance (P < 0.2) in the univariable analyses was performed. ‡During the first 24 h postoperatively.
PONV: postoperative nausea and vomiting, OR: odds ratio. *Multivariable logistic regression analyses were performed after adjusting for the following variables: body mass index, and baseline heart rate ≥ 60 beats/min. †Interaction analyses for the overall PONV between the baseline PONV risk and number of prophylactic agents were performed. ‡This included 4,357 patients who received no or single prophylactic agent for PONV. §This included 5,559 patients who received single or dual prophylactic agents for PONV.
