Specific features are described for all steps of the algorithm in the
corresponding sections of the manuscript. A provisional diagnosis may
be adequate in patients for whom the differential diagnosis has been
sufficiently narrowed such that further investigations are unlikely to
alter management, when invasive testing has unacceptable risks, or
when such tests are declined by the patient.
