All are true of standardized mortality ratio except:
|A||Expressed as rate per year|
|B||Can be adjusted for age|
|C||Can be used for events other than death|
|D||Ratio of observed deaths to expected deaths|
If the ratio had value greater than 100, the risk of mortality rises.
1. SMR permit adjustment for age and it is of value if the event of interest is occurrence of disease rather than death.
2. Other standardization techniques
3. Life table
4. Regression techniques
5. Multivariate analysis
