The screening list should be signed by the doctor, and the dispensing list should be signed by the attending doctor. If it is formal, it should be the signature of the administrator. As for the subject identification (signature) code table, it is necessary to know whether signature is needed. The correct one should be identification rather than signature, so you don't need to sign, but you should have the full name of the subject. Only the identification code table needs to be recorded for the subjects who successfully entered the group, and the screening and inclusion table needs to be filled in.
