CRP and ulcerative colitis: In patients with ulcerative colitis, there were no significant correlations between serum elafin and inflammatory markers, i.e., ESR (p = 0.41; R = 0.13), CRP (p = 0.38; R = 0.14), fecal calprotectin (p = 0.78; R = −0.05), and the clinical activity index PUCAI (p = 0.23; R = 0.19).
