随机方法(请说明由何人用什么方法产生随机序列):

多中心临床试验中普遍采用的方法是以中心分层,然后在各中心内进行区组随机化,称为分层的区组随机化。本研究以视神经脊髓炎亚型(分为脊髓炎、视神经炎)为分层因素,在每个层内进行区组随机化,区组长度为4-6,各区组长度在试验阶段保密。由独立统计师使用SAS 9.4统计软件产生随机编码,受试者按照1:1随机分为试验组和对照组。

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

A commonly adopted method in multicenter clinical trials is stratified randomization by study center, followed by block randomization within each center, known as stratified block randomization. In this study, neuromyelitis optica subtypes (categorized as myelitis or optic neuritis) were used as stratification factors, with block randomization performed within each stratum. The block size ranged from 4 to 6, and the specific block lengths remained concealed during the trial phase. An independent statistician generated the randomization codes using SAS 9.4 statistical software, and subjects were randomized in a 1:1 ratio to either the experimental group or the control group
