Data are expressed as the number of patients (percentile). Group P: patients who received pyridostigmine as the reversal agent. Group S: patients who received sugammadex as the reversal agent. Postoperative pain was counted when the measured score was over 3 using the numerical rating scale. Postoperative nausea and vomiting (PONV) were counted as follows from the nursing care records and antiemetics administration history. *: indicates 2-sided P value < 0.05. Effect size:
