RT Journal A1 Filippone M, Bonetto G, Cherubin E, Carraro S, Baraldi E T1 CHildhood course of lung function in survivors of bronchopulmonary dysplasia JF JAMA JO JAMA YR 2009 FD October 7 VO 302 IS 13 SP 1418 OP 1420 DO 10.1001/jama.2009.1419 UL http://dx.doi.org/10.1001/jama.2009.1419 AB To the Editor: Bronchopulmonary dysplasia (BPD) is the primary respiratory complication of premature birth, associated with a reduced maximal lung function that may carry a risk of a chronic obstructive pulmonary disease (COPD)–like phenotype developing later in life.1 There is little prospective evidence about the evolution of lung function in long-term survivors of BPD.
