随机方法(请说明由何人用什么方法产生随机序列):

随机序列由独立于临床招募与结局评价的第三方统计师,采用 SPSS 26.0 统计软件生成完全随机数字序列,制定随机分配表。

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

The random sequence was generated by an independent statistician who was blinded to patient recruitment and outcome assessment using SPSS 26.0 software. A simple random number sequence was created to formulate the random allocation schedule.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

本研究采用双盲设计,受试者、临床医师、结局指标评估人员、实验室检测人员及数据统计分析人员均不清楚受试者分组情况与干预方案。肠道菌群移植制剂及安慰剂在外观、性状、包装、给药方式、疗程周期上保持完全一致,严格控制混杂偏倚。研究全程实施分组隐匿,直至所有病例随访结束、数据录入完成并锁定后,由第三方统计师统一揭盲。

Blinding:

Blinding: A double-blind design was adopted. All participants, clinicians, outcome assessors, laboratory technicians and statisticians were masked to group assignment. The FMT preparation and placebo were identical in appearance, texture, packaging and administration. Blinding was maintained until data collection and database lock, followed by centralized unblinding.
