Risk Factor | Estimate ± SE† | OR (95% CI) | p |
---|---|---|---|
Dactylitis | −2.36 ± 0.59 | 0.094 (0.030, 0.300) | < 0.0001 |
Hip arthritis | 2.44 ± 0.75 | 11.45 (2.65, 49.49) | 0.0011 |
Baseline platelet count | −0.0032 ± 0.0019 | 0.99 (0.99, 1.000) | 0.0890 |
↵† The estimates and their SE can be used to compute the OR and CI for a given risk factor as well as to predict the odds of sacroiliitis for patients with different combinations of risk factors. OR is equal to the exponential value of the estimate, e.g., the odds of sacroiliitis for patients with hip arthritis is e2.44 = 11.4 times that for patients without.
