A randomized controlled trial, often called an “RCT,” is a method used to test the effectiveness of treatments, medications, or interventions. In an RCT, participants are divided into two groups randomly. One group receives the treatment being tested, while the other group receives a placebo. The group that gets the treatment is chosen randomly, like picking names out of a hat. This helps make sure the results are fair.
By comparing these two groups, researchers can determine if the treatment actually produces the desired effects or if it’s just by chance. RCTs are crucial to provide reliable evidence to guide medical decisions and improve patient care.« Back to Glossary Index
