Meta-analysis of restrictive versus liberal transfusion thresholds: Mortality at 30 days

Meta-analysis of restrictive versus liberal transfusion thresholds: Mortality at 30 days
This plot shows risk ratios for mortality at 30 days in randomized trials published through November 2017 that compared a restrictive transfusion threshold (transfusing for a hemoglobin level below 7 to 8 g/dL) with a liberal transfusion threshold (transfusing for a hemoglobin level below 9 to 10 g/dL) in a variety of medical and surgical populations including adults and children. Refer to UpToDate for recommendations regarding specific transfusion thresholds in specific populations.
M-H: Mantel-Haenszel method for computing the risk ratio.
