  • Randomised controlled trial (RCT) (often ‘randomised trial’)

    A trial in which people are randomly assigned to two (or more) groups:  one (the experimental group) receiving the treatment that is being tested, and the other (the comparison or control group) receiving an alternative treatment, a placebo (dummy treatment) or no treatment. The two groups are followed up to compare differences in outcomes to see how effective the experimental treatment was. Such trial designs help minimise experimental bias.
