Note
Responses to the study question “Which procedures were used to evaluate this patient’s clinical eligibility for PEA? Please select all that apply.” Data are the percentage of patients for which these procedures were performed. This question was asked only for patients clinically evaluated in a specialist pulmonary hypertension center (Europe/United States) or department (Argentina/Japan). Probability test pairwise comparisons across rows. CT: computed tomography; MRI: magnetic resonance imaging; PEA: pulmonary endarterectomy; RHC: right heart catheterization; V/Q: ventilation/perfusion.
