Association between the endoscopic score and laboratory and clinical parameters. Endoscopic activity of CD was assessed using the scoring described previously [24] (Table 2). The original Rutgeerts score [25] was developed for evaluation of anastomosis lesions after ileocolic resection, but we adapted it for the most serious lesion of the entire region observed by enteroscope. The Spearman’s rank correlation coefficient (ρ) for non-parametric correlations is presented
