After February 2022, ask researchers for raw data

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 CRF 填写
对于每一位进入本研究的受试者,数据录入由临床研究者或由研究者授权的人员完成。CRF 中的数据应与原始记录一致,试验中的任何观察、检查结果均应及时、正确、完整、清晰、规范、真实地填写于 CRF 中,不得随意更改。CRF 中所有项目均需填写,不得空项或遗漏。
2 CRF 审核 研究者在每位受试者当前访视结束后,在规定时间内完成 CRF 的填写,审核并提交。研究者应及时回复来自监查员、数据管理员、医学审核人员的质疑。在数据清理完成后,研究者对填写完毕的CRF签名确认。
3 数据核查 研究者填写并提交 CRF 后,监查员、数据管理员以及医学人员应对数据进行审核,审核发现的问题,以质疑的形式要求研究者回答。数据清理完毕后,CRF 需研究者签字确认。
4 数据审核与数据锁定 临床试验完成后,由主要研究者、统计专家、数据管理员共同进行统计分析前的审核。任何决定都需要有文件记录。 经审核确定数据正确无误后,对数据库进行锁定。数据库锁定后的数据需妥善保存备查,数据库提交统计分析专家进行计。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:
|
1 fill in CRF
For each subject who entered the study, the data entry was completed by the clinical investigator or the person authorized by the investigator. The data in CRF shall be consistent with the original record, and any observation and inspection results in the test shall be filled in CRF timely, correctly, completely, clearly, normatively and truthfully, and shall not be changed at will. All items in CRF shall be filled in and shall not be left blank or omitted.
2 audit CRF
After each subject's current visit, the investigator completed, reviewed and submitted the CRF within the specified time. Researchers should promptly respond to queries from monitors, data administrators, and medical reviewers. After data cleaning, the researchers signed the completed CRF.
3 data verification
After the investigator fills in and submits CRF, the monitor, data manager and medical personnel shall review the data, and ask the investigator to answer the questions found in the audit in the form of query. After data cleaning, CRF needs to be signed by researchers.
4 data audit and data locking
After the completion of the clinical trial, the main researchers, statistical experts and Data Administrators jointly conduct the audit before the statistical analysis. Any decision needs to be documented. After the data is verified to be correct, lock the database. The data locked in the database shall be properly stored for future reference, and the database shall be submitted to statistical analysis experts for calculation.
