Effectiveness of TNF inhibitor in reduction of concomitant CS dose. a Concomitant CS dose in the CS without TNF-i group (n = 22) and TNF-i with CS group (n = 20). b Comparison of reduction of concomitant CS dose between the CS without TNF-i group (n = 22) and TNF-i with CS group (n = 20). (*P < 0.05, by Wilcoxon signed-rank test). c Comparison of proportion of concomitant CS dose < 7.5 mg. (*P < 0.05, by Fisher’s exact test) (last observation carried forward). Abbreviations: CS, corticosteroid; TNF-i, TNF inhibitors; DAIBD, disease activity index for intestinal Behcet’s disease
