^*Time to revascularization = adjusted geometric mean from date of the index acute myocardial infarction to procedure;

^†From April 1, 2001, to December 31, 2001;

^‡Annual percentage of change = 100 × [exp (β)–1] adjusted for age and sex from linear regression models;

^§P value of diabetes-year interaction. CABG Coronary artery bypass graft; DM Diabetes mellitus; PCI Percutaneous coronary intervention
