Randomized Control Trial (RCT)

A randomized control trial is a specific type of research experiment in which scientists attempt to control factors that are not under direct experimental control. This type of trial carries significant evidentiary weight because it minimizes the chances of outside influences changing the results of the experiment. There are numerous situations where a randomized control trial might be used, including during the process of drug development. During this trial, participants are allocated to different groups that receive different types of treatments. The researchers will try to keep most factors uniform so that any differences in the outcomes of the group can be attributed to specific variables that are being altered, such as the type or dosage of drug administered. The ultimate goal is to control confounding factors to deliver a useful comparison that can help researchers draw conclusions from the experimental change.
