So now we know that cross over studies have carry on effects but then it can save more on cost due to less participants needed. My question is why is cross over more utilised in phase I and II?

Hi. Could you please explain what is the difference between a crossover study and a double dummy study? Also, what does a "double dummy parallel study" mean? Thanks in advance.
