Clinical Trial: A work that reports on the results of a clinical study in which participants are assigned to receive one or more interventions so that researchers can evaluate the interventions on biomedical or health-related outcomes.
Observational Study: A work that reports on the results of a clinical study in which participants may receive diagnostic, therapeutic, or other types of interventions, but the investigator does not assign participants to specific interventions.
Case-control and Cohort studies are examples of observational studies. A case-control study is a primary research method that compares people with a condition to people without it. A cohort study is a research study that follows a group of people over time to see if a specific characteristic is linked to a health outcome.
Randomized Control Trial: A work that reports on a clinical trial that involves at least one test treatment and one control treatment, concurrent enrollment and follow-up of the test- and control-treated groups, and in which the treatments to be administered are selected by a random process.
