所有原始数据将如实、及时、准确地记录在电子病例报告表(ECRF)中。两名专业人员将独立输入ECRF中的数据,以确保数据的准确性。录入数据后,不允许随意修改数据。项目组将召开审核会议,审核确认数据并锁定数据库。锁定的数据库和编码表将提交给统计员进行分析。研究结束后,应备份并保留原始数据,以防止数据损坏。

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

All the original data will be recorded in the electronic case report form(eCRF) truthfully, timely, and accurately. Two professionals will input the data in eCRF independently to ensure the accuracy of the data. After data entry, it is not allowed to modify data at will. The project team will hold an audit meeting to review and confirm the data and lock the database. The locked database and coding table will be submitted to the statistician for analysis. After the end of the study, the original data should be backed up and retained to prevent data damage.
