Impact of switching to new spirometric reference equations on severity staging of airflow obstruction in COPD: a cross-sectional observational study in primary care
BACKGROUND: Severity of airflow obstruction in chronic obstructive pulmonary disease (COPD) is based on forced expiratory volume in one second expressed as percentage predicted (FEV(1)%predicted) derived from reference equations for spirometry results. AIMS: To establish how switching to new spirome...
