At each assessment time point, three non-consecutive 24-hour dietary recalls (including at least one weekend day) will be conducted to estimate participants’ typical daily energy and macronutrient intake. The recalls will be administered by trained dietitians through face-to-face or telephone interviews, and dietary data will be analyzed using validated nutrition analysis software based on the Chinese Food Composition Table (2022 or equivalent). In addition, two random 24-hour recalls per month

随机方法(请说明由何人用什么方法产生随机序列):

随机序列由独立统计员(D.T.)使用计算机生成的区组随机化方法产生。区组大小设为4和6的随机组合。随机化采用分层区组随机设计,分层因素包括:(1)研究中心;(2)性别。随机序列由主中心的数据管理系统保存,研究人员在受试者完成导入期并确认符合随机化条件后,通过中央随机化平台获取分配结果。

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

The random allocation sequence will be generated by an independent statistician (D.T.) using a computer-based block randomization method, with randomly varying block sizes of 4 and 6. Stratified block randomization will be applied with the following stratification factors: (1) study center and (2) gender. The randomization list will be stored in the central data management system, and investigators will obtain allocation results via the central randomization platform after confirming eligibility for randomization.

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:

数据分析者:设盲。数据分析者(如统计员)在分析阶段不知道分组身份,分组以代码形式(如A组/B组)呈现直至分析完成。

Blinding:

Data analysts: Blinded. Statistical analysts will receive coded group data (e.g., Group A/B) and remain blinded to group identity until all primary analyses are completed to minimize analytical bias.

是Yes

共享原始数据的方式(说明:请填入公开原始数据日期和方式,如采用网络平台,需填该网络平台名称和网址):

研究公开发表后一年内通过ResMan平台http:/hwww.medresman.org.cn/ogin.aspx共享部分去标识化参与者原始数据

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):

Within one year after publication, a portion of de-identified participant raw datasets will be shared via the ResMan.

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:

数据采集将通过纸质问卷进行,数据采集完毕后将进行电子化录入。所有电子化数据包括电子化的调查问卷数据和实验室检测数据都将被储存于哈尔滨医科大学安全并有密码保护的服务器上;数据将长期保存于哈尔滨医科大学。所有纸质问卷以及知情同意书将被保存在哈尔滨医科大学带锁文件柜中,

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

Data collection will be carried out through paper-based questionnaires, and will be entered electronically after data collection is completed. All electronic data, including electronic questionnaire data and laboratory test data, will be stored in a safe and password-protected server of Harbin Medical University; the data will be stored in Harbin Medical University for a long time. All paper questionnaires and informed consent forms will be kept in a locked filing cabinet at Harbin Medical University.
