Figure 3

Comparison of emphysema severity and pulmonary function between three groups according to TLR4 expression. (A) Mean emphysema scores increased as TLR4 expression decreased. (B) Cases of severe emphysema were more common among patients with low TLR4 expression levels. (C) Airflow limitation was more severe at lower TLR4 expression levels. FEV1, Forced expiratory volume in one second; FVC, Forced vital capacity.
