BACKGROUND The six-second spirometry has been proposed as an alternative to diagnose airflow limitation, although its prognostic value in patients with chronic obstructive pulmonary disease (COPD) remains unknown. The purpose of this study was to determine the prognostic value of the postbronchodilator forced expiratory volume in 1 second (FEV1)/forced(More)
RATIONALE Global Lung Function Initiative recommends reporting lung function measures as z-score, and a classification of airflow limitation (AL) based on this parameter has recently been proposed. OBJECTIVES To evaluate the prognostic capacity of the AL classifications based on z-score or percentage predicted of FEV1 in patients with chronic obstructive(More)
