Fig. 2From: Steroid insensitive fixed airflow obstruction is not related to airway inflammation in older non-smokers with asthmaUnivariate relationships between lung function measurements and BAL IL-17a. No significant correlations were demonstrated and similar findings were seen with other cytokines. FEV1/FVC=forced expiratory volume/forced vital capacity, K=reflects lung compliance, X5=reactance at 5Hz, BAL=bronchoalveolar lavage, IL=interleukinBack to article page
