Metrics to compare Cardiovascular Disease Mortality

Metric	Definition	Interpretation if rate is > 1	Calculation
SMR (Standardized Mortality Ratio)	The relative rate of death due to CVD between group* and reference^	Group is more likely to die of CVD than reference	$\frac{\text{Standardized Death Rate Group}}{\text{Standardized Death Rate Reference}}$
rSMR (Relative SMR)	The relative rate of death due to CVD over all cause	CVD (compared to other causes) has a higher rate of death in group than reference	$\frac{\text{CVD SMR Group}/\text{All Cause SMR Group}}{\text{CVD SMR Ref}/\text{All Cause SMR Ref}}$
PMR (Proportionate Mortality Ratio)	Ratio of percent cause of death due to CVD between group and reference	CVD accounts for a larger percentage of deaths in group than reference	$\frac{\#\text{CVD Deaths Group}/\#\text{Total Death Group}}{\#\text{CVD Deaths Ref}/\#\text{Total Death Ref}}$

^*group = specified Asian American subgroup by sex;

^{^}reference = all Non-Hispanic Whites
