Mortality, event rate, and fatality all apply to myocardial infarction. Numbers in parentheses are 95% credible intervals. The best performing and worst performing districts (ie, the individual districts with the lowest and highest values, respectively) could be different for each outcome.
*
Proportion of myocardial infarction events that result in death before hospital admission.
†
Proportion of hospital admissions due to myocardial infarction that result in death within 28 days of admission.
