随机方法(请说明由何人用什么方法产生随机序列):

本研究采用分层中央随机方法,根据血管闭塞部位(颈内动脉,大脑中动脉 M1/M2)和中心分层,利用中央随机系统设置动态随机区组,每中心设置入组试验组和对照组受试者比例为1:1。各中心采用竞争入组的方式对每位入组受试者分配随机号。

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

The randomization sequence will be generated automatically in a centralized computer at the contract research organization at Day 1. Patients are stratified by site of vessel occlusion into one of the following strata: (1) ICA occlusion, (2) MCA-M1, and (3) MCA-M2 occlusion.
