The patient's don't see the progress of others taking the drug. That would go against all rules of confidentiality and medical privacy. The doctors can see who's benefitting but John Smith can't look across the hall and see Joe Blow doing better...

People drop out because they know they are not getting the drug and so thus there is no motivation to stay in the trial. That simple.
