  1. Data are presented as the means ± SE and in parentheses (median, minimum-to-maximum ranges). IIP: idiopathic interstitial pneumonia; IPAF: interstitial pneumonia with autoimmune features; N: number; yr: years; FVC: forced vital capacity; FEV1: forced expiratory volume in 1 second; DLCO: carbon monoxide diffusing capacity of the lung.
