Both the Participant in the Experimental Group Who Receives an Experimental

Both the participant in the experimental group who receives an experimental treatment and the participant in the control group who receives the control treatment are considered to be participants in therapeutic research. Why is this?

A) A patient in an experimental research study who elects to be a member of the experimental group knows he or she will be receiving the experimental treatment.
B) Each patient who is consented to be a research participant in an experimental study, in which the treatment has potentially beneficial results, has the potential to receive a therapeutic intervention.
C) The research is designed to measure the effect of the therapeutic treatment, as compared with the usual therapeutic treatment; hence, this is therapeutic research.d.Each participant is blind to treatment.
