Correlation between serum periostin levels and clinical variables related to asthma
Serum periostin levels were found to be significantly correlated with asthma severity (Spearman’s rho [r]=0.41, p < 0.001) and BMI z score (r= -0.31, p < 0.001), whereas no correlations were found with age, disease duration, accompanying atopic diseases such as allergic rhinitis and atopic dermatitis, asthma control status, total IgE levels, blood eosinophil counts and lung function parameters (Table 3).
