Comparison of Global Initiative for Chronic Obstructive Pulmonary Disease 2013 Classification and Body Mass Index, Airflow Obstruction, Dyspnea, and Exacerbations Index in Predicting Mortality and Exacerbations in Elderly Adults with Chronic Obstructive Pulmonary Disease

Abstract

The GOLD 2013 classification performed well in identifying individuals at risk of exacerbations, and its predictive ability for exacerbations was better than that of the BODEx index, although the predictive ability for mortality in elderly adults with COPD was poor for both indices.
