Clinical trial recruitment begins by the company holding the trial determining what type of trial they will hold and which types of participants they are most interested in including. At this point in the trial process, recruitment is generally voluntary, and participants are selected solely on a volunteer process. Those in charge of the process then determine how the participants in the trial will be grouped; these groups are typically random, blind, or known as a control group because they are administered a fake treatment.
random sample
A treatment is imposed, ex.) making the participants take a certain medicine instead of just allowing them to do what they please and see how they heal.
