tail. He or she should be informed that he or she is at liberty
to abstain from participation in the study and that he or she
is free to withdraw his or her consent to participation at any
time. The doctor should then obtain the subject"s freely-given
informed consent, preferably in writing.
10. When obtaining informed consent for the research project the
doctor should be particularly cautious if the subject is in a
dependent relationship to him or her or may consent under duress.
In that case the informed consent should be obtained by a doctor
who is not engaged in the investigation and who is completely in-
dependent of this official relationship.

4. The refusal of the patient to participate in a study must

5. If the doctor considers it essential not to obtain informed

stated in the experimental protocol for transmission to the in-

care, the objective being the acquisition of new medical know-
