: ANCOVA = analysis of covariance; 6MWD = six-minute walk distance; EQ-5D = EuroQol 5-dimensions questionnaire; LPH = Living With Pulmonary Hypertension questionnaire; NT-proBNP = N-terminal prohormone of brain natriuretic peptide; PVR = pulmonary vascular resistance; WHO = World Health Organization.
: Note: P values used to determine statistical significance are given in bold.
a: Variables are ordered in the sequence of testing.
b: Test of normality of the data.
c: Mantel–Haenszel estimate P value for incidence of clinical worsening.
d: Stratified log-rank test P value for time to clinical worsening.
e: Patients enrolled before CHEST-1 analysis plan Amendment 3 used the Modified Borg Dyspnea Scale.
