The Kaplan-Meier survival graphs showing cumulative remission rates for patients who achieved clinical remission. In the weekly GMA arm (dotted line), patients received one session per week, while in the intensive arm (solid line), patients received two GMA sessions per week. The mean time to remission for the 16 patients in the weekly GMA arm who achieved clinical remission was 35.4 ± 5.3 days vs 21.7 ± 2.7 days in the 19 patients of the intensive GMA arm who achieved clinical remission, P = 0.0373 by Wilcoxon-Mann–Whitney test. GMA = granulocyte and monocyte adsorptive apheresis
