Table 3– Multivariable logistic regression model for predicting good functional capacity (definition based on metabolic equivalents) after pulmonary endarterectomy

Variables	OR (95% CI)	p-value
Pulmonary compliance mL·mmHg⁻¹	2.13 (1.14–3.97)	0.018
Age^#	0.96 (0.94–0.98)	<0.001
Female sex	2.29 (1.3–4.0)	0.003
P_aO₂^¶	1.08 (1.05–1.11)	<0.001
T_LCO % predicted^¶	1.04 (1.01–1.06)	0.001
TAPSE⁺	0.64 (0.37–1.08)	0.096

P_aO₂: arterial oxygen tension; T_LCO: transfer factor of the lung for carbon monoxide; TAPSE: systolic displacement of the tricuspid annular plane. Global p-value of the model <0.001; c statistic 0.85; shrinkage 0.92. ^#: per year; ^¶: per unit; ⁺: ≥14 mm versus <14 mm.
