Time trends in risks of myocardial infarction incidence, death without myocardial infarction, and death after myocardial infarction by sex and income group (Hazard Ratios of time periods, reference: period 1 (2006–2008)). Hazard Ratios estimated by multistate survival models; 95%-CI bootstrapped (with replacement) using 1000 replications; all analyses are controlled for age in single-year age groups (as second-degree polynomial); MI myocardial infarction
