Data are presented as n or mean±sd (minimum–maximum). BMI: body mass index; PAH: pulmonary arterial hypertension; NYHA: New York Heart Association. For oxygen use, only “Yes” descriptive statistics are reported. #: n=120 patients. *: p<0.05; **: p<0.01; ***: p<0.001. Asterisks follow the higher mean for the fatigue dimension.
