Educational attainment | No. of events/No. of participants | Incidence per 1000 person-years (95% CI) |
---|---|---|
Low | 419/7068 | 7.31 (6.40, 8.35) |
Medium | 134/4286 | 5.86 (4.88, 7.03) |
High | 122/3713 | 5.10 (4.21, 6.17) |
Poisson regression was used to estimate age- and sex-adjusted incidence rates by level of educational attainment.
