Table 3. Comparison of treatment response and the δFC level according to the drug for remission induction.

Variable	Oral PRS (n=29)	Anti-TNF-α (n=16)	p-value
Rate of CR after 6 months of treatment	18 (62.1)	14 (87.5)	0.1280
Rate of ER after 1 year of treatment	12 (41.4)	10 (62.5)	0.5004
δFC measured at 6 weeks after treatment (%)	52.5	80.0	0.3550

Values are presented as number (%).

Delta FC (δFC) was calculated as follows: (FC pre-treatment – FC 6 weeks post-treatment)×100/(FC pre-treatment), as a percentage.

PRS: prednisolone, Anti-TNF-α: anti-tumor necrosis factor alpha, CR: clinical remission, ER: endoscopic remission, FC: fecal calprotectin.
