随机方法(请说明由何人用什么方法产生随机序列): |
本试验采用随机、开放设计,采用分层区组随机化方法进行受试者随机入组。分层因素为受试者年龄(按年龄≥65、65>年龄≥18划分)、基于DSA的Hasan闭塞分型(A型、B型),按试验组与对照组1:1的比例并基于上述分层因素产生受试者随机表,并导入至中央随机化系统(IWRS)中,整个试验过程中通过IWRS统一分配受试者随机号。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
This trial adopted a randomized and open design, and the stratified block randomization method was used to randomize the participants. The stratification factors were the age of the subjects (divided by age ≥65, 65> age ≥18), DSA-based Hasan occlusion classification (type A, type B), according to the ratio of 1:1 between the experimental group and the control group and based on the above stratification factors, the subject randomization table was generated, and imported into the central randomization system (IWRS), and the subject randomization number was uniformly assigned through IWRS throughout the trial. |

是否公开试验完成后的统计结果: Calculated Results after the Study Completed public access: |
公开/Public |
|
盲法: |
1. 开放标签设计 - 受试者和主要研究者知晓分组情况 - 无法对治疗过程进行盲法(血管内治疗 vs 药物治疗差异明显) 2. 终点盲法评估 - 主要终点:由独立于试验的评价中心进行盲态评估 - 临床终点委员会(CEC)对主要终点事件进行判定 - 评估者不知晓受试者的分组情况 |
|
Blinding: |
1. Open-Label Design Subjects and primary investigators are aware of group assignments Unable to blind the treatment process (obvious difference between endovascular treatment vs medical therapy) 2. Endpoint Blinded Assessment Primary Endpoint: Conducted by independent evaluation center with blinded assessment Clinical Endpoint Committee (CEC) adjudicates primary endpoint events Assessors are unaware of subjects' group assignments |
