Data collection
The data of participants will be collected according to the study protocol. Case report forms (CRFs) will be used to ensure the appropriate collection of necessary data. Routine auditing of the study documentation will be performed to ensure the quality of the data recorded in CRFs. To ensure the timeliness of the data, the CRFs will be completed within 3 working days following every visit. All data collected in CRFs will be transferred to an electronic database for further data collection and management. The confidentiality policy is outlined in an informed consent form and will be ensured during the data collection.
