- An SMR of greater than 1 indicates that, after adjusting for the effect of differences in age and sex structure between the geographic areas, there is a higher mortality rate in Middlesex-London than in Ontario.
- An SMR of less than 1 indicates that, after adjusting for the effect of differences in age or sex structure between the geographic areas, there is a lower mortality rate in Middlesex-London than in Ontario.
