Randomisation

The process by which patients in a clinical trial are randomly assigned to different treatments. Randomisation minimises the differences among groups by equally distributing people with particular characteristics among all the trial arms. It is considered the best way to assess the efficacy of a given medical treatment.

Randomised controlled trial (RCT)

In a RCT, the research participants are randomly allocated, usually by computer, to either the control or the active arm of the study. Those in the active arm are given the new treatment, while those in the control group are given either an inert placebo or the current best available treatment. Researchers will be interested in whether more of the patients in the active arm are showing signs of improvement than in the control group. RCTs are considered to be the ‘gold standard’ in medical research.
