Randomised controlled trial (RCT)
The gold-standard trial design, where participants are randomly assigned to treatment or control groups.
What it is
A Randomised Controlled Trial (RCT) is a type of study where participants are randomly assigned to either a treatment group or a control group. This means that some people will receive the new treatment being tested, while others will receive a standard or placebo treatment. The goal is to compare the outcomes of both groups to see if the new treatment is safe and effective.
How it works
In an RCT, participants are randomly assigned to a treatment or control group by a computer or a researcher. This random assignment helps to ensure that both groups are similar in terms of age, health, and other factors. The treatment group receives the new treatment, while the control group receives the standard or placebo treatment. Researchers then compare the outcomes of both groups, such as how many people experience side effects or how well they respond to treatment.
Why it matters
Understanding RCTs is important for patients and carers because it helps them make informed decisions about their treatment options. RCTs provide the strongest evidence for whether a new treatment is safe and effective, which can help doctors and patients decide whether to use it. By following the results of RCTs, patients and carers can stay up-to-date with the latest research and treatment options.
