随机方法(请说明由何人用什么方法产生随机序列):

本研究由张俊麒采用计算机随机数法进行随机化分组,即:将连续双节段符合手术标准的患者按照先后顺序编号后,将编号输入SPSS软件,对每一个编号产生一个随机数,并创建2个分割点,根据此随机数及分割点将所有病人随机分为3组,3组病例数量相同

Randomization Procedure (please state who generates the random number sequence and by what method):

This study used computer-generated random numbers for randomization. Specifically, patients who met the surgical criteria were numbered in order of presentation. The numbers were entered into SPSS software, which generated a random number for each number and created two cut-off points. Based on these random numbers and cut-off points, all patients were randomly divided into three groups with equal numbers of cases in each group.
