Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | 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.~Red Blood Cell Transfusion: Transfusion of packed red blood cell units | 39 | 1,755 | OG000 |
| Group 2 | 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.~Red Blood Cell Transfusion: Transfusion of packed red blood cell units | 43 | 1,749 | OG001 |
