随机方法(请说明由何人用什么方法产生随机序列):

本研究采用区组随机法,本研究选择区组的大小为4,即每4例为一个区组,每4例受试者实现试验组和对照组为1∶1。随机数字表由统计师采用SAS软件产生。按照试验组和对照组1︰1、多中心、区组随机,产生编号001-136受试者的随机分配方案。采用不透光的牛皮纸信封将136例受试者所接受处理(试验组和对照组)的随机安排每个人一个信封,每个中心指定专人管理随机信封,按照受试者入组的顺序拆开随机信封,接受对应的处理分配。受试者麻醉后进行随机分组。

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

In this clinical investigation, block randomization method is adopted, the size of block group is 4. That is, every 4 cases is a block group, and every 4 subjects realized the ratio of test group and control group is 1∶1. The table of random numbers is generated by statisticians using SAS softwa

盲法:

本研究采用对受试者设盲,不对研究者设盲的单盲研究方法。为尽可能保证结果的无偏倚性和准确性,故本研究指定由评价医生(非手术医生)进行主要指标盲态评价。设盲工作由统计师完成。

Blinding:

In clinical investigation, the subjects are blinded, but the researchers are not blinded. In order to ensure the unbiased and accurate results as much as possible, the evaluators (non-surgeons) are designated to conduct blind evaluation of the main indicators in this clinical investigation. Blind work is completed by statisticians.
