Glossary term explanation

Randomized controlled trials

Randomized controlled trials are studies in which patients or healthy volunteers are assigned at random (purely by chance) to receive one or more clinical interventions. One or more of the interventions is the active treatment being tested. Another of the interventions is the control against which the active treatment is being tested. The control is, typically, the standard practice or treatment, a placebo treatment, or no intervention at all.
