Video Summary

A randomized controlled trial (RCT) is a type of experimental research design in which participants are randomly assigned to one of two or more groups, such as a treatment group or a control group. The goal is to determine the effectiveness of an intervention or treatment by comparing the outcomes between the groups. Patients who are in a control group receive a placebo instead of the active treatment. The groups are then followed over time to see if there is a difference in the outcome measures (such as symptoms, quality of life, or survival) between the groups.
