随机方法(请说明由何人用什么方法产生随机序列):

由研究医生提前使用计算机随机生成的随机数字进行随机分组,具体随机结果分装不透明信封,交由各分中心独立研究助手来保管,本中心医生收治合格病例后,签署知情同意书后,由保管随机分组结果的研究助手拆开信封,按照随机分组结果将该病例纳入试验组或对照组,进行相应的治疗并收集相关信息。

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

Randomization is carried out using random numbers generated in advance by the investigating physician through a computer, and the specific random results are packaged in opaque envelopes, which are kept by independent research assistants at each sub-center. After the physician at this center admits a qualified case, and the informed consent form is signed, the research assistant who keeps the randomization results opens the envelope and assigns the case to the experimental group or the control group according to the randomization results, conducts the corresponding treatment, and collects relevant information.
