Figure 2 Flowchart of study patients (n = 53) according to treatment groups. *Relapse rates did not differ between the surgery and steroid groups (P = .1, NS). The time to relapse was longer in the surgery group (P = .03); however, the range was wide. †Serologic relapse occurred in only 1 patient in this group (overall, 3 patients had only serologic relapse [without a biochemical relapse]). AZA, azathioprine; MM, mycophenolate mofetil. Gastroenterology 2008 134, 706-715DOI: (10.1053/j.gastro.2007.12.009) Copyright © 2008 AGA Institute Terms and Conditions
