A study in which the people taking part are assigned by chance (randomisation) into groups (such as the control group or the study group). The groups are managed in exactly the same way except they are given different treatments, or exposed to a risk factor of interest. Outcomes are measured at specific time points and any difference in response between the groups is assessed statistically. This method is used to reduce bias. HTAI
