Following publication of this article [1], readers identified an error in Table 4 that the table title was “Incidence of secondary efficacy variables in the 24-h postoperative period”. Authors have checked that “the incidence of no emesis, use of rescue medication or nausea” should be the primary outcome, and the title of table 4 should be corrected to “Incidence of primary and secondary efficacy variables in the 24-h postoperative period”. We thank the reader for “this very meaningful comment”.
