随机方法(请说明由何人用什么方法产生随机序列):

合格的志愿者被分层随机化后进入3种不同干预方式的组(MCC组、AX组、MAX组)。所有志愿者将随机给予一个特定的编号,从 001 开始。编号排列无固定次序,由电脑随机产生随机分组将使用随机数字,具体步骤为:1)对于合格受试受试者分别按照性别、BMI进行分层;2)对每一研究对象产生一个对应的随机数字;3)根据事先设定的各个处理组样本量大小,按随机数字顺序选择相应的样本数量,分配到不同的处理组。

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

Eligible volunteers are stratified and randomised into 3 different intervention groups (MCC group, AX group, MAX group). All volunteers will be randomly given a specific number, starting from 001. There is no fixed order for numbering, and random numbers will be used to generate random groups randomly by the computer in the following steps: 1) for eligible subjects subjects are stratified according to gender and BMI, respectively; 2) a corresponding random number is generated for each study subject; 3) according to the pre-determined size of the sample size of each treatment group, the corresponding sample sizes will be selected according to the order of the random numbers, and assigned to the different treatment groups.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

一、数据采集: 本试验在整个干预过程中将有 3个干预阶段,并进行问卷调查和生物样本采集(粪便样本在干预期每个周收集一次,洗脱中期收集一次,血液样本在阶段干预起点和终点各采集一次)。在规定时间,通知参加者到指定的地点进行相应的调查、检查和样本的收集,由专人填写项目实施记录表。 二、数据管理 数据管理包括数据搜集阶段的数据检查核对,数据整理阶段的预处理、编码、录入、校对和清理等。主要是为了净化原始数据,使其系统化、条理化,确保数据质量,确保其正确性和科学性。数据管理主要涉及三方人员:研究人员、质量控制组和数据管理员。研究人员的主要职责之一是将志愿者的信息正确、清晰的填入预先设计好的研究报告表和各项问卷,并在表上签名。质控组成员要定期前往试验现场,监督各个研究人员的试验进度及研究报告表的填写。在数据送到数据管理员之前,质控组需要对每一份收到的表格进行一系列的核对。数据管理员的主要职责是将研究报告表和各项问卷上的信息准确、可靠的输入计算机,并保证数据库和所有资料的安全和保密。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

1. Data collection: This trial will have 3 intervention phases throughout the intervention with questionnaires and biological samples collection (faecal samples will be collected once per week of the intervention period, once in the middle of the elution period, and blood samples will be collected once at each of the phase intervention start and end points). At the specified time, participants are notified to go to the designated place for the corresponding survey, examination and sample collection, and a person is assigned to fill in the project implementation record form. Second, data management Data management includes data checking and verification in the data collection stage, and preprocessing, coding, entry, proofreading and cleaning in the data collation stage. The main purpose is to purify the original data, make it systematic and organised, ensure the quality of the data, and ensure its correctness and scientificity. Data management mainly involves three parties: researchers, quality control team and data managers. One of the main responsibilities of the researchers is to fill in the pre-designed study report forms and various questionnaires with correct and clear information from the volunteers and to sign the forms. Members of the quality control group were to visit the trial site regularly to monitor the progress of the trial and the completion of the study report forms by individual researchers. The QC team is required to perform a series of checks on each form received before the data is sent to the data manager. The main responsibility of the data manager is to enter the information on the study forms and the various questionnaires into the computer accurately and reliably, and to ensure that the database and all information is kept secure and confidential.
