Outcome
- Type
- OTHER_PRE_SPECIFIED
- Title
- Incidence: Blood Transfusion
- Description
- Occurrence of event
- Time frame
- Date of MI to 15 months
- Population
The intention to treat (ITT) principle. Patients were analysed according to their allocated intervention, irrespective of whether the patient's actual management complied with the allocated intervention. As specified in the protocol, other endpoints will be collected where possible and therefore there is missing data.
