Spirometric Interpretation and Clinical Relevance According to Different Reference Equations.

ABSTRACT:

Background

Global Lung Function Initiative (GLI)-2012 reference equation is currently suggested for interpretation of spirometry results and a new local reference equation has been developed in South Korea. However, lung function profiles according to the different reference equations and their clinical relevance have not been identified in chronic obstructive pulmonary disease (COPD) patients.

Methods

Our cross-sectional study evaluated Choi's, Korean National Health and National Examination Survey (KNHANES)-VI, and GLI-2012 reference equations. We estimated the percentages of predictive forced expiratory volume in one second (FEV₁) and airflow limitation severity according to reference equations and analyzed their associations with patient reported outcomes (PRO
