Data are presented as mean score ± SD or interquartile range [IQR (range)] or n (%) of patients. Data were analyzed using analysis of variance (continuous variables) or the χ² test (incidence variables), Kruskal–Wallis rank sum test was also used for rank data. Group R: epidural anaesthesia with 0.75% ropivacaine; Group MR: epidural anaesthesia with 0.75% ropivacaine + 2% mepivacaine (Volume 1:1); Group M: epidural anaesthesia with 2% mepivacaine; SD standard deviation; IQR: interquartile range;There were no significant differences among the groups (P > 0.05)
