Receiver operating characteristic (ROC) curve for serum calprotectin levels, CRP and ESR to discriminate patients with high and moderate disease activity. The ROC analysis showed that at a cutoff point of 397.05 ng/ml, calprotectin showed a maximum AUC of 0.608 (95% CI 0.372–0.845); P = 0.401, whereas CRP at a cutoff point of 60 mg/l showed an AUC = 0.704 (95% CI 0.457–0.952); P = 0.114. Besides, ESR at a cutoff point of 67.5 mm/h had an AUC = 0.579 (95% CI 0.336–0.823); P = 0.540
