I believe that future research should address this issue by narrowing down what the best treatment possible out there is. By just comparing a new drug and a placebo you are only testing one variable seeing if the new drug works and what side effects it causes. There are a million different types of treatments out there for certain conditions. For example, when you have a cold there are so many different types of medications to choose from, but which one is the best? By testing the new drug, placebo, and a drug already in place you are able to compare and contrast if the new drug is even worth continue testing. By doing this you are ultimately finding out which drug is the best and saving time on going through all the trials if its not improving
