Conditional Poisson regression analysis for differences in CV risk factor measurement among patients with RA and IBD compared with their matched controls
| RA | N (%) | IBD | N (%) | |
|---|---|---|---|---|
| Time period | ||||
| 1 year before index date | 1.22 (1.11 to 1.33) | 3171 (59) | 1.33 (1.23 to 1.44) | 4840 (53) |
| 1 year after index date | 1.25 (1.12 to 1.35) | 3200 (59) | 1.26 (1.16 to 1.38) | 4428 (48) |
| Within 5 years from index date | 1.08 (1.04 to 1.14) | 3941 (73) | 1.10 (1.05 to 1.15) | 5473 (60) |
The incidence rate ratios were adjusted for ethnicity, age, gender and deprivation.
CV, cardiovascular; IBD, inflammatory bowel disease; N, number; RA, rheumatoid arthritis.
