All are true of standardized moality ratio except:
Expressed as rate per year
Can be adjusted for age
Can be used for events other than death
Ratio of observed deaths to expected deaths
Expressed as rate per year Standardized moality ratio (SMR) = Expected death/ Observed deaths x 100 If the ratio had value greater than 100, the risk of moality rises. * SMR permit adjustment for age and it is of value if the event of interest is occurrence of disease rather than death. * Other standardization techniques * Life table * Regression techniques * Multivariate analysis
