Variations in all-cause mortality, premature mortality and cause-specific mortality among persons with diabetes in Ontario, Canada
Authors' conclusion
The observed mortality variations suggest a need to address inequality gaps in diabetes care for persons with diabetes living in the lowest income areas.

As reported in the abstract
Hazard ratio (95% CI)
Lowest incomevs Highest incomeall-cause mortality; fully adjusted
1.26(1.25–1.27)
Lowest incomevs Highest incomepremature mortality; fully adjusted
1.44(1.42–1.46)

0.46(0.46–0.47)
Immigrantsvs Long-term residentspremature mortality; fully adjusted
0.40(0.40–0.41)
Observational data: associations, not effects.
Further findings
Cause-specific mortality (cardiovascular, cancer, respiratory, external causes)
- Similar HRs by income and immigrant status for cause-specific mortality, except cancer mortality, where the income gradient was attenuated
- Competing risk analysis (Fine-Gray)
