View source for Randomized clinical trial

A study in which the participants are assigned by chance to separate groups that compare different treatments. Neither the researchers nor participants can choose which group participants are assigned to. Using chance to assign people means that the groups will be similar and the treatments they receive can be compared objectively. At the time of the trial, it is not known which treatment is best. It is the patient's choice to be in a randomized trial. {{stub}} [[category:definitions]]
