Odds ratios for colectomy according to cause of acute pancreatitis, adjusted for baseline disease extent of ulcerative colitis
| Cause of pancreatitis | n | OR (95%CI) | P value |
| No pancreatitis (reference) | 3256 | 1.00 | |
| Autoimmune | 13 | 1.65 (0.35-7.66) | 0.525 |
| No pancreatitis (reference)1 | 3256 | 1.00 | |
| Aminosalicylate-induced | 10 | 1.76 (0.67-8.41) | 0.480 |
| No pancreatitis (reference)1 | 704 | 1.00 | |
| Thiopurine-induced | 13 | 1.31 (0.32-6.60) | 0.651 |

Non-pancreatitis patients (reference) who were treated with either aminosalicylates or thiopurines. Among 3307 UC patients, those with biliary pancreatitis (n = 6) and idiopathic pancreatitis (n = 9) were excluded from the analysis, and the results from the remaining 3292 are shown. UC: Ulcerative colitis.
