Fig 1 Distributions of patients based on the Global Initiative for Chronic Obstructive Lung Disease (GOLD) grading system that indicates the severity of airflow obstruction and on the modified Medical Research Council (mMRC) functional dyspnea scale. (Solid areas = grade 4; shaded areas = grade 3; dotted areas = grade 2; open areas = grade 1.)

Fig 2 Kaplan-Meier curves of long-term survival are shown with the patients stratified by severity of airflow obstruction according to Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria: control group (solid line), mild group (GOLD 1 [dotted line]), moderate group (GOLD 2 [dashed line]), and severe group (GOLD 3 [broken line]). *Log rank test compared with the control group.
