Data are presented as mean ± SD. MFI = Multidimensional Fatigue Inventory; US CAMPHOR = United States Cambridge Pulmonary Hypertension Outcome. See Table 2 legend for expansion of other abbreviation.
a
Probability value for differences between week 1 and week 3 MFI and US CAMPHOR scores.
b
MFI scores range 4-20; higher scores indicate increased fatigue.
c
US CAMPHOR total symptom and quality of life scores range 0-25; energy scores range 0-10; breathlessness scores range 0-8; mood scores range 0-7; total activity scores range 0-30; higher scores indicate worse symptoms, activity, and quality of life.
