是否共享原始数据:

IPD sharing

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):

在国内公网能查看到的数据存放平台ResMan(临床试验公共管理平台 http://www.medresman.org.cn)共享,预计共享时间为研究结束后6个月内。

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

The domestic publicly accessible data will be deposited and shared via ResMan (Clinical Trial Public Management Platform, http://www.medresman.org.cn), and are expected to be released within six months after the completion of the study.

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:

1.数据采集 临床研究研究者或经授权的CRC收集CRF数据(纸质形式或PDF等电子文本形式)。CRF数据将录入EXCEL数据库。 2.病例报告表设计 CRF设计按照完全遵循试验方案原则,做到全面完整、简明扼要;易于理解;方便数据录入和满足统计分析需求。 3.数据录入与传输 临床研究研究者或经授权的CRC将CRF数据录入至EXCEL数据库,待录入和SDV完成后通过邮件将数据库传输给数据管理员进行数据清理。 4.数据核查和数据质疑的管理 数据管理员将对EXCEL数据库进行数据清理,将疑问数据整理成质疑表清单发送给研究者确认以解决数据疑问,数据管理员依据研究者签字答疑后的质疑表对EXCEL数据库或由研究者/经授权的CRC对CRF进行更新(如需)。 5.数据库锁定及资料归档 各方对数据如无异议,可执行数据库正式锁定并签订数据库锁定记录文件,保证数据的准确性和完整性。 6.临床研究的数据处理和统计分析 凡自身对照资料可以采用配对 t 检验,两组均数比较采用成组 t 检验,后者需进行方差齐性检验,对非正态分布或方差不齐的数据进行适当的变量转换,待满足正态方差齐后,用转换的数据进行 t 检验;若转换数据仍不能满足正态方差齐要求,改用 t’检验或秩和检验;方差齐但变异系数太大(如 CV>50%)的资料应用秩和检验。 7.结果判定 以试食组与安慰剂对照组试验终点各项功效指标组间统计学对比结果为主要判定依据;同时结合各组内基线(D0)与试验结束(D61±1)指标自身前后对比结果综合评价。

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

1. Data CollectionData on Case Report Forms (CRFs) shall be collected by clinical investigators or authorized Clinical Research Coordinators (CRCs) in paper format or electronic formats such as PDF. CRF data will be entered into an Excel database.2. Design of Case Report Forms (CRFs)CRFs shall be designed in full compliance with the trial protocol, featuring comprehensive and concise content, easy readability, convenient data entry, and compatibility with statistical analysis requirements.3. Data Entry and TransmissionClinical investigators or authorized CRCs shall input CRF data into the Excel database. Upon completion of data entry and Source Data Verification (SDV), the database shall be sent to the data manager via email for data cleaning.4. Management of Data Review and Data QueriesThe data manager shall perform data cleaning on the Excel database. Suspicious data will be compiled into a query list and sent to investigators for confirmation to resolve data discrepancies. The data manager shall update the Excel database based on investigator-signed resolved query forms; investigators or authorized CRCs shall update the CRFs if necessary.5. Database Locking and Document ArchivingIf all parties raise no objections to the data, the formal database lock shall be implemented with a signed database lock record to guarantee data accuracy and integrity.6. Data Processing and Statistical Analysis for Clinical ResearchPaired t-test shall be adopted for self-controlled data. The independent samples t-test shall be used for intergroup comparison of means, preceded by homogeneity of variance test. For data with non-normal distribution or unequal variances, appropriate variable transformation shall be performed; t-tests shall be conducted on transformed data once normality and homogeneity of variance are satisfied. If transformed data still fail to meet normality and homogeneity of variance criteria, the t’ test or rank-sum test shall be applied. Rank-sum test shall be used for data with homogeneous variance but excessively large coefficient of variation (CV > 50%).7. Outcome AssessmentThe primary assessment basis shall be the intergroup statistical comparison of all efficacy endpoints between the test food group and the placebo control group. Comprehensive evaluation shall also incorporate intra-group self-comparisons between baseline (Day 0, D0) and trial termination (Day 61±1) indicators.
