∥AMI: Acute myocardial infarction.
†W30D: In-and-out-of-hospital mortality within 30 days, attributing the outcome to all hospitals by fraction of time spent in each hospital for transferred patients.
‡S30D: In-and-out-of-hospital mortality within 30 days, patients treated at one hospital only.
§IH30D: In-hospital mortality within 30 days, for each hospital admission.
