The single breath nitrogen test and mortality – A 38 years follow up

Spirometry data predict mortality, but are less sensitive to detect dysfunction in small airways as compared to the slope of phase III (the N2 slope) of the single breath nitrogen test. The association between the N2 slope and mortality has been studied with conflicting results. In the present study the prognostic importance of the N2 slope was tested taking spirometry variables into account.
