Crude Analysis between Crohn's Disease or Ulcerative Colitis and CRC
| Case |
Control |
OR | |
|---|---|---|---|
| IBD | 39 (2.0) | 21 (1.1) | 1.91 (1.12-3.26) |
| No IBD | 1882 (98.0) | 1900 (98.9) | p=0.018 |
| Crohn's | 2 (0.1) | 2 (0.1) | 1.0 (0.14-7.11) |
| No Crohn's | 1919 (99.9) | 1919 (99.9) | p=1.00 |
| UC | 35 (1.8) | 16 (0.8) | 2.21 (1.22-4.01) |
| No UC | 1886 (98.2) | 1905 (99.2) | p=0.0074 |
UC and CD columns do not add up to 39 IBD cases since this definition also included a few respondents who had surgery for IBD but did not specify subtype.
