The example you cite below would best modeled as a MedicalTrial. Basically,
a MedicalTrial is a controlled clinical trial in the traditional sense
(people recruited to study a particular intervention, divided into
treatment and control groups), whereas MedicalStudy is a more general
umbrella type that covers these and other kinds of studies, including
uncontrolled observational
studies<http://en.wikipedia.org/wiki/Observational_study>
(MedicalObservationalStudy)
like the Nurses' Health Study where a group of people are observed over a
period of time.

Does that help clarify? I'll look at making the documentation crisper here.
