ABG, PFTs and BAL lymphocytes analysis were similar among the three groups. There were no differences among the three groups either at the time of the surgical lung biopsy or after the post-follow-up reclassification.
ABG = arterial blood gas analysis; BAL = Bronchial alveolus lavage; PFT = pulmonary function tests.
