The Role of Pulmonary Function Test for Pulmonary Arterial Hypertension in Patients with Connective Tissue Disease

Table 4

Logistic regression analysis for the predictive value of pulmonary function parameters.

Parameters	OR	95% CI	value
TLC (%)	0.911	0.817–1.017	0.096
FEV1/FVC (%)	1.044	0.950–1.147	0.371
DLCO (%)	4.813	1.039–22.300	0.045

OR: odds ratio; 95% CI: 95% confidence interval. Bold values are statistically significant (). FVC: forced vital capacity; FEV1: forced expiratory volume in 1 second; DLCO: diffusing capacity of the lung for carbon monoxide.
