Red blood cell transfusions stratified by anemia classification. Anemia was classified as none (hemoglobin ≥ 120 g/L for women and ≥ 130 g/L for men), mild (hemoglobin 110 to 119 g/L for women and 110 to 129 g/L for men), moderate (hemoglobin 80 to 109 g/L for both), and severe (hemoglobin < 80 g/L for both). (d = day; RBC = red blood cell.).
