  • *Incidence rate ratio estimated using log-binomial regression models with count of hospitalizations within each disease group as outcome and diabetes as a binary independent variable with ‘no diabetes’ as reference. All models are adjusted for age and calendar year. Additional adjustment for gender in model for the total study population.

  • †P value for interaction term between gender and diabetes as a test for difference in strength of association between diabetes and risk of hospitalization.

  • AMI, acute myocardial infarction; CAD, coronary artery disease; CVD, cardio vascular disease.
