Clinical Trials Use Comparison Groups to Compare Medical Strategies and Treatments

Abstract

Nengjun Yi

Clinical trials are investigations of novel tests and treatments to see how they affect human health outcomes. To compare medical methods and treatments, most clinical studies employ comparison groups. If one group outperforms the other, the results will reveal that. This is normally done in one of two ways: one group is given an existing treatment for a problem, while the other is given a new treatment. Clinical trials are medical research investigations that involve patients. Interventional and observational trials are the two most common types of trials or studies. The goal of interventional trials is to learn more about a certain intervention or treatment.
