Figure 2. Selected Clinical Variables Across the Spectrum of Pulmonary Vascular Disease.
Spider plots of selected clinical variables across the spectrum of pulmonary vascular disease including disease comparators. Presented are characteristics of cardiac physiology: (A) N-terminal-pro-brain natriuretic peptide (NT-proBNP), (B) 6-minute walk distance (6MWD), (C) sleep study (% recording time <90% saturation), (D) ground glass on chest computed tomography (CT), (E) diffusing capacity for carbon monoxide (DLCO), and (F) echocardiographic (ECHO) right atrial (RA) volume index. *Significant difference across PH or comparator groups. Median values shown. Comparator group 5 not included in statistical comparisons. †Significant difference at level 0.05 between comparators and PH participants within group. G = group.
