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

Each subject will correspond to a standard CRF (Case Report Form) collection form. After the original data is filled into the CRF by trained data collectors (including clinicians, nurses, medical students, etc.), at least two data entry personnel from each center will enter the data into the EDC (Electronic Data Capture system) according to the principle of double data entry.
