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

1. The trial data should be traceable, and the data in the trial report, case report form, clinical trial data sheet and other documents should be consistent and traceable to the original test record. 2. The data that significantly deviate from the clinical trial protocol or are outside the range of clinical acceptability shall be verified, and the investigator shall make necessary explanations. 3. After the completion of the clinical trial, the investigator should collect, organise and analyse the clinical trial data in a standardised manner. 4. The original data generated in the process of clinical trials should be entered into the case report form, the clinical trial investigator shall sort out the clinical trial data, and the person in charge of clinical trial statistics shall conduct statistical analysis of the clinical trial data. After the analysis, it was concluded that the principal investigator should complete the clinical trial report based on the conclusions of the clinical trial. All raw data for clinical verification are stored in the medical institutions that undertake clinical trials.
