随机方法(请说明由何人用什么方法产生随机序列):

使用分层区组随机化方法,将患者按1:1:1的比例随机分配到对比治疗组1、比治疗组2或保守治疗组。区组大小为4,分层因素为孕周。随机化通过基于网络的手机应用程序Ratjin(www.jinlingshu.com)进行。患者根据入组时间分配随机的序列号,并提供了相应编号和盲处理的药物。所有试验人员和患者均不知道治疗分配情况。

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

Using a stratified block randomization method, patients were randomly assigned to comparison treatment 1, comparison treatment 2, or conservative treatment in a ratio of 1:1:1. The block size was 4, and stratification factors included gestational age and participating center. The randomization was done via the web-based mobile app Ratjin (www.jinlingshu.com). Patients were assigned random serial numbers based on enrollment time, and were provided with the corresponding numbered and blind treated drugs. Treatment assignment was not known to all participants and patients.
