随机方法(请说明由何人用什么方法产生随机序列): |
由联络员将区组长度定为 4,具体步骤:采用 Excel 中 Rand 函数生成 0-1 之间均匀分布的随机数,将其复制至 Excel 另一行中生成随机数字 1,将每个区组中的随机数字由小到大排列,得到序号 R,R1-R2 为 试验组,R3 到 R4 为对照组。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
The randomization sequence was generated by the study coordinator using the RAND() function in Microsoft Excel software to produce uniformly distributed random numbers between 0 and 1. For each block of length 4, four random numbers were generated and sorted in ascending order, resulting in a sorting rank R (1 to 4) within each block. The first two subjects (R1, R2) in each block were assigned to the experimental group (low bacterial diet group), and the last two (R3, R4) were assigned to the control group (aseptic diet group). The generation of the randomization sequence was performed independently by the study coordinator, and the allocation was concealed |

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): |
本研究产生的去标识化个体数据(包括患者基线特征、感染结局、饮食依从性等)以及统计分析代码,可在论文发表后向通讯作者合理索取。数据共享需符合北京协和医院伦理委员会的规范及患者知情同意书的条款。因涉及患者隐私及伦理限制,部分原始数据(如姓名、住院号)不予公开 |
|
The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url): |
Deidentified individual participant data (including baseline characteristics, infection outcomes, dietary adherence, etc.) and statistical analysis codes generated for this study will be available upon reasonable request to the corresponding author after publication. Data sharing will comply with the regulations of the Peking Union Medical College Hospital Ethics Committee and the terms of the informed consent. Raw data containing personal identifiers (e.g., names, medical record numbers) will not be shared due to privacy and ethical restrictions |
|
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: |
本研究的数据采集包括:患者人口学信息、临床特征、饮食干预记录、每日体温测量值、血常规结果、感染事件(粒缺伴发热、血培养阳性、大便培养阳性等)、腹泻发生情况、住院时长及体重变化等。所有数据由研究协调员使用电子病例报告表(eCRF)进行双人独立录入,并定期与原始病历核对以确保准确性。数据管理采用密码保护的数据库,仅授权研究人员可访问。数据将保存至研究结束后的10年 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data collected in this study include demographic information, clinical characteristics, dietary intervention records, daily temperature measurements, blood routine results, infectious events (febrile neutropenia, positive blood culture, positive stool culture, etc.), occurrence of diarrhea, length of hospital stay, and body weight changes. All data will be double-entered independently by study coordinators using an electronic case report form (eCRF) and regularly verified against source medical records to ensure accuracy. Data management will be performed using a password-protected database accessible only to authorized research personnel. Data will be retained for 10 years after study completion. |
