What is a Clinical Trial?
Although there are many definitions of clinical trials, they are generally considered to be biomedical or health-related research studies in people that follow a pre-defined protocol. Clinical trials include both interventional and observational types of studies.
- Interventional studies are those in which the research subjects are assigned by the investigator to a treatment or other intervention, and their outcomes are measured.
- Observational studies are those in which individuals are observed and their outcomes are measured by the investigators.
