随机方法(请说明由何人用什么方法产生随机序列):

由研究人员将研究志愿者分配一个唯一的序列号(例如,001、002、003、004、005……),确定随机数字分组的研究人员不能参与纳入受试者,以防止信息泄露。在整个研究期间,将使用唯一编号作为志愿者的ID,以确保匿名和保密。对于这些唯一编号中的每一个,使用随机化软件R 4.1.0生成一个随机序列,用于将唯一编号(参与者)随机分配给益生菌组或安慰剂组。在研究过程中,志愿者的治疗分发者、数据收集者和数据分析人员将对随机顺序视而不见。随机化序列将由独立的项目管理员维护,只有在重大安全问题或进行中期和最终数据分析时,才会取消盲。

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

Study volunteers are assigned a unique serial number by a dedicated researcher (e.g. 001, 002, 003, 004, 005...). . A unique number will be used as the volunteer's ID throughout the study period to ensure anonymity and confidentiality. For each of these unique numbers, randomization software R 4.1.0 was used to generate a random sequence that was used to randomly assign the unique numbers (participants) to either the probiotic or placebo groups. During the study, the volunteers' treatment dispensers, data collectors, and data analysts will be blind to the random order. The randomised sequence will be maintained by an independent project manager, and blinding will only be removed for major safety issues or for interim and final data analysis.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

随机双盲双模拟:受试者和干预者都不知道受试者接受的是实验组还是对照组的治疗。

Blinding:

Randomized double-blind: Neither the subject nor the intervenor knows whether the subject is receiving treatment in the experimental or control group.
