Routine Pulmonary Function Test Can Estimate the Extent of Tuberculous Destroyed Lung

Table 2

Correlation of destroyed lung scores with pulmonary function (Spearman rank correlation).

Variables	Correlation coefficient	𝑃 value
FEV1 (L)	−0.78	0.001
FEV1 (% predicted)	−0.62	0.018
FVC (L)	−0.61	0.021
FVC (% predicted)	−0.76	0.002
FEV1/FVC (%)	0.17	0.551

FEV₁: forced expiratory volume in 1 s, FVC: forced vital capacity.
