Odds ratios (calculated from logistic regression models) for coronary heart disease risk factors by educational level

| Primary | Secondary | High* | |
| *Odds ratio and 95% confidence intervals adjusted for age, gender, diagnosis, centre, and furthermore for body mass index through logistic regression modelling, taking high education as reference (that is, relative risk of high education is equal to 1). | |||
