Quizplus · Accepted Answer

A double-blind study involves both the researcher and participants being unaware of who is receiving the treatment and who is receiving the placebo. This reduces bias and increases the reliability of the results. In addition, a new heart disease treatment is likely to be a significant health concern, making it essential to have trustworthy results before it is widely used.
