Table 3 Correlation between sarcoidosis stage and pulmonary function parameters

Pulmonary functional parameters	Stage by CXR (0/I/II/III/IV)		Stage by HRCT (I/II/III/IV)
Pulmonary functional parameters	Correlation index	p value	Correlation index	p value
FVC	−0.073	0.413	−0.125	0.163
FEV1	−0.168	0.06	−0.247	0.006
FEV1/FVC	−0.46	< 0.001	−0.618	< 0.001
DLCO	−0.153	0.139	−0.353	< 0.001
DLCO%	−0.182	0.096	−0.380	< 0.001

Bivariate spearman correlation analysis was performed.
FVC forced vital capacity, FEV1 forced expiratory volume in one second, DLCO carbon monoxide diffusing capacity
