Remission rates over time in patients who were started azathioprine. ∗Five of these patients were treated with 5-ASA or budesonide before azathioprine and were resistant to these. Two additional patients who had recently started azathioprine were excluded for the analysis. ∗∗Two patients were lost to follow-up after remission and 1 had remission with allogeneic bone marrow transplantation.
