[20] Therefore, chronic rejection explains long-term morbidity in most lung-transplant recipients, [ 23 ] [ 24 ] the median survival roughly 4.7 years, about half ...
DPB is classified as a form of "primary bronchiolitis", which means that the underlying cause of bronchiolitis is originating from or is confined to the bronchioles.
