Text: The ratio of complete response (no PONV for 2 h) was higher for groups O8 and R than for group O4 as follows : 80 % (n = 32) for groups O8 and R versus 58 % (n = 23) for group O4 during the first postoperative 2 h (p = 0. 04), 90 % (n = 36) for groups O8 and R versus 76 % (n = 30) for group O4 over 24 h (2-24 h) (p = 0. 09), and 98 % (n = 38) for groups O4 and O8 versus 100 % (n = 40) for group R over the next 24 h (24-48 h) after surgery (p = 0. 36).
