Perioperative transfused allogenic RBC units.

Group I: all patients (𝑛=101)		Group II: all patients (𝑛=234)
Men (𝑛=36)	6 RBC units	Men (𝑛=93)	15 RBC units
Women (𝑛=65)	21 RBC units	Women (𝑛=141)	20 RBC units
Total	27 RBC units	Total	35 RBC units
Group I: anemic patients (𝑛=24)		Group II: anemic patients (𝑛=32)
Men (𝑛=1)	6 RBC units	Men (𝑛=5)	1 RBC unit
Women with Hb≥12 <13 g/dL (𝑛=16)	3 RBC units	Women with Hb≥12<13 g/dL (𝑛=22)	7 RBC units
Women with Hb<12 g/dL (𝑛=6)	13 RBC units	Women with Hb<12 g/dL (𝑛=5)	4 RBC units
Total	22 RBC units	Total	12 RBC units

Group I: 8% (8/101) of all patients received 27 RBC units, respectively, 29% (7/24) of anemic patients received 22 RBC units. Group II: 6% (15/234) of all patients received 35 RBC units, respectively, 19% (6/32) of anemic patients received 12 RBC units. RBC: red blood cells.
