Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Other - Red Blood Cell Transfusion

Active comparator: Liberal Transfusion Strategy - Red blood cell transfusion - One unit of packed red cells is transfused following randomization followed by enough red blood cell units to raise the hemoglobin concentration above 10 g/dL any time the hemoglobin concentration is detected to be below 10g/dL during the hospitalization for up to 30 days.

Active comparator: Restrictive Transfusion Strategy - Permitted to receive a red blood cell transfusion if the blood count is below 8 g/dL and the physician believes it is in the patient's best interest. A transfusion will be strongly recommended if the blood count drops to less than 7 g/dL. If the patient has symptoms of angina (e.g., chest discomfort described as pressure or heaviness) that do not go away with medication, a blood transfusion will be ordered regardless of the blood count.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
Yes
What data in particular will be shared?
Limited access data (i.e., records without personal identifiers) will be prepared by the Data Coordinating Center (DCC) and sent to the NHLBI Biologic Specimen and Data Repository Information Coordinating Center (BioLINCC) within 3 years after the end of the final patient follow-up or 2 years after the main paper of the trial has been published, whichever comes first. The Trial data set will include baseline patient characteristics, follow-up status, and clinical outcome data. The data will be released to requesting institutions and investigators in accordance with BioLINCC policy.
When will data be available (start and end dates)?
Available to whom?
Available for what types of analyses?
How or where can data be obtained?
