Both随机方法(请说明由何人用什么方法产生随机序列):
由独立的随机化统计师应用SAS9.4及以上版本产生受试者随机表和药物随机表。受试者随机设计:采用分层区组随机化方法,以既往是否接受过RSV单克隆抗体(是/否)作为分层因素,按照1:1的比例随机进入试验组或安慰剂组。药物随机设计:采用区组随机化方法,按照1:1的比例随机进入试验组或安慰剂组。Randomization Procedure (please state who
generates the
random number sequence and by what method):
An independent randomization statistician generated subject randomization tables and drug randomization tables using SAS version 9.4 or higher. Subject randomization design: A stratified block randomization method was employed, with prior exposure to RSV monoclonal antibodies (yes/no) as the stratification factor. Subjects were randomly assigned to the treatment group or placebo group in a 1:1 ratio. Drug Randomization Design: A block randomization method was employed, with subjects randomized in a 1:1 ratio to either the trial group or the placebo group.是否公开试验完成后的统计结果:
