Exclusion of registration If, at any point in time, the patient or the investigator decides to withdraw the registration of certain patients from the central registry, they may be excluded from future submissions of information to the central registry. The information previously incorporated in the decision to withdraw the registration of the central registry will remain in the same. In case the investigator wants to withdraw its participation in the registry, it should be notified one month in advance to the scientific advisory committee. The information previously uploaded to the central registry will be removed from the analysis as well as future communications.
