What is a 'controlled' clinical trial?
There are different clinical trials. When working in a research company that conducts trials, it is important to be fully versed in all aspects of your profession and be able to distinguish the differences. Share your knowledge with the interviewer.
"In a controlled trial, one group of patients will be given an experimental drug or treatment, while a second group is given either a standard treatment for the illness or a placebo. It helps us determine the differences in the patients' response to the trial drug compared to a standard treatment or no treatment."
"A controlled clinical trial occurs when one group of patients is given a placebo or a commonly used treatment, and another group is given the experimental treatment/drug. In this study, the workers conducting the trial are aware of which patients received the experimental drug and those who did not."
