As Dr.Simon mentioned about placebo-controlled trials, which is A “dummy” device or drug is used on one group of patients and compared to patients with the real one, or sometimes called a ‘sugar pill. Or a fake ultrasound device in a bone healing study.

So, Do you think Placebo-controlled trials: Are they ethical? Are they necessary ? Also, what are the advantages and disadvantages of using PCTs ?

I think PCTs is rarely used in some circumstances like asthma patients for example. The advantage of using PCTs is Zero risk of overdose.Also, Placebos are always better than no treatment.
