Figure 3 Remission rates in cytapheresis therapy in patients with ulcerative colitis exposed to anti-tumor necrosis factor-α treatment and in those unexposed to anti-tumor necrosis factor-α treatment. The remission rates in patients with ulcerative colitis (UC) exposed to anti-tumor necrosis factor-α (TNF-α) treatment are 27.8% and 31% (mean: 29.4%), and those in patients with UC unexposed to anti-TNF-α treatment are 40.3% and 48% (mean: 44.15%), respectively.
