AbstractBackground: So far, there is limited experience in comparing the recently published GLI-2012 reference values (Eur Respir J, 2012. 40(6): p. 1324-43) with the ECCS/ERS 1993 recommendations still mostly used all over Europe.Methods: We used the equations of both of these publications for calculation of predicted values of 799 male patients (mean age 67 yrs, range 26-91 yrs). Spirometry was performed in all of these subjects with a pneumotach (MasterScreen; CareFusion, Hoechberg, Germany).
