Problem
5.1
As
in the hypothetical study of breathlessness in Problem 3.1, consider
five patients followed for 6 days before and after admission in
a palliative care program. This time, however, you are given the
severity of breathlessness in terms of a Likert scale from 1 (mild
breathlessness) to 4 (overwhelming breathlessness). For this exercise
a "case" of severe breathlessness is defined as a score
of 3 or 4.
