| Logistic regression shows that the association between sacroiliitis and CARD15 variants is independent of known CARD15 related phenotypes or HLA-B27. | |||
| CI, confidence interval; OR, odds ratio. | |||

| HLA-B27 | 0.201 | 3.48 | 0.51 to 23.81 |
| Ileal involvement | 0.517 | 1.84 | 0.29 to 11.49 |
