Spirometric classifications of COPD severity as predictive markers for clinical outcomes: the HUNT Study

2020-11-05

Abstract excerpt

<h4>ABSTRACT</h4> <h4>Rationale</h4> GOLD grades based on percent-predicted FEV 1 poorly predicts mortality. Studies have recommended alternative expressions of FEV 1 for the classification of COPD severity and they warrant investigation. <h4>Objective</h4> To compare the predictive abilities of ppFEV 1 (ppFEV 1 quartiles, GOLD grades, ATS/ERS grades), FEV 1 z-score (FEV 1 z-score quartiles, FEV 1 z-score grades),...
