CT-Data management (Recruitment and Delivery phase)
During the conduct phase of the trial, the data quality should be monitored, see CT SOP Data Management, point 4.2. Verification, validation and coding should be performed according to the data management plan and described in the Data Management Report. Possible changes in the data entry application must be documented, see DEA Change Log. When all data have been recorded correctly, the database should be locked, see Database Lock Form.
