随机方法(请说明由何人用什么方法产生随机序列):

受试者将被随机分配进入常规治疗结合米非司酮辅助治疗组(试验组),或常规治疗组(对照组)。受试者将有50%的概率进入试验组,50%的概率进入对照组。受试者及其临床医生都不能选择其被分入的治疗组,但在随机分组后,受试者的临床医生会知晓其将接受的治疗。

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

Subjects will be randomly assigned to either conventional treatment combined with mifepristone (trial group) or conventional treatment (control group). Subjects will have a 50% chance of entering the trial group and a 50% chance of entering the control group. Neither the subject nor their clinician can choose the treatment group into which they are assigned, but after randomization, the subject's clinician will be informed of the treatment they will receive.
