Clinical trials also permit testing and monitoring of the effect of an intervention on a large number of people to ensure that any improvement as a result of theÂ intervention occurs for many people and is not just a random effect for a one person. Clinical trials: Trials to evaluate the effectiveness and safety of medications or medical devices by monitoring their effects on large groups of people. This is because computer simulation and animal testing can only tell us so much about how a new treatment might work and are no substitute for testing in a living human body.
