From: Relationship between age and bronchodilator response at diagnosis in adult-onset asthma
Correlations between age at diagnosis of adult-onset asthma and bronchodilator reversibility in FEV1a) in mL in SAAS cohort (Spearman’s test), b) in percentages in SAAS cohort (Spearman’s test), c) in mL in COREA cohort (Pearson’s test), d) in percentages in COREA cohort (Pearson’s test). One outlier removed from c) and d). FEV1 = Forced expiratory volume in one second, BDR = bronchodilator response
