Which medical condition, disease, disorder, syndrome, illness, or injury is researched?
Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.
Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
