Figure 2From: Delay of airway epithelial wound repair in COPD is associated with airflow obstruction severityRelationships between mean speed of bronchial epithelial wound closure and FEV 1 . Bronchial epithelial wound closure in non COPD (triangle, n = 7) and COPD patients (square, n = 13) was monitored for 18 h, and the mean speed of wound closure (MSWC) was calculated. p = 0.01.Back to article page
