Definition and frequency of IBD5 haplotypes in Crohn’s disease patients and controls
| Haplotype definition | Haplotype frequency | Significance CD v controls | ||||||
|---|---|---|---|---|---|---|---|---|
| IGR2060a_1 | IGR2198a_1 | IGR3096a_1 | CD (n = 330) | UC (n=457) | Controls (n = 870) | p Value | RR (95% CI) | |
| p values in bold are significant (p<0.05) after Bonferroni correction factor of 8 (number of haplotypes tested for association). | ||||||||
| CD, Crohn’s disease; IBD, inflammatory bowel disease; RR, relative risk; UC, ulcerative colitis. | ||||||||
