IPF: idiopathic pulmonary fibrosis, BP: bacterial pneumonia, HC: healthy controls, VC: vital capacity, FEV1: forced expiratory volume in 1 second, FVC: forced vital capacity, and DLCO: diffusing capacity of the lung for carbon monoxide.
Data represent the mean ± SD.
Significant differences versus the HC were evaluated using Mann-Whitney U test.
