Comparison of each marker as a predictor of CR at the end of GMA therapy. The ΔFC value at week 1 was demonstrated the most accurate predictor of CR at the end of GMA (AUC = 0.852, p = 0.002) among the pMayo score, FC concentration, CRP value and ΔCRP. (AUC = 0.842, 0.663, 0.666 and 0.784. p = 0.003, 0.158, 0.151 and 0.014) CR: clinical remission, GMA: granulocyte and monocyte adsorptive apheresis, ΔFC: the reduction rate of fecal calprotectin, pMayo: partial Mayo score, FC: fecal calprotectin, CRP: C reactive protein, ΔCRP: the reduction rate of CRP
