*Model 1 was adjusted for age, Charlson-Deyo index, previous heart failure, hypertension, previous myocardial infarction, diabetes mellitus, income, rural residence, annual hospital volume, calendar period of treatment, hospital clustering, physician clustering and Local Health Integration Network clustering.
†Model 2 was adjusted for all variables in model 1 and further adjusted for sufficiency of cardiac monitoring.
