Q
Standardised mortality ratio
A
The standardised mortality ratio is a tool used to compare mortality within different populations while taking into account the effect of confounding factors such as age and sex.
It is the observed deaths divided by the expected deaths (sometimes multiplied by 100).
An SMR of 100 (or 1) indicates that the mortality in the group being studied is the same as the standard population. An SMR of greater than 100 indicates a higher than expected amount of mortality.
