Receiver operating characteristic (ROC) curves. The area under the curve (AUC) for (a) serum periostin in 83 samples (b) sputum periostin 83 samples and (c) the comparison of serum periostin and blood eosinophils in the same 67 samples. The data was analysed using STATA 11 software. The performance characteristics of the periostin (a and b) and blood eosinophil (c) variables were examined by calculating AUC which was considered statistically significant when p < 0.05
