Note. WG = willing group, UWG = unwilling group, M=mean.
a
χ2 Chi-square for difference between willing and unwilling for the treatment decisions that could be made in advance of treatment.
b
Importance rating is a 5-point likert scale ranging from 1= ‘not at all important’ to 5= ‘extremely important’.
c
Weighted rating =percent could make treatment decision x importance rating.
c
t= t-test.for difference between wiling and unwilling for weighted rating.
