	All patients (n = 1286)	African American (n = 861)	White (n = 352)	Other (n = 73)	p‐value a
Overall	2.1 (1.4)	2.1 (1.3)	2.2 (1.5)	2.2 (1.4)	.43
Hb 10–9 g/dL	1.3 (0.49)	1.5 (0.6)	1 (0)	No Data	.18
Hb 8.9–8.0 g/dL	1.8 (1.3)	1.4 (0.5)	2.1 (1.6)	1.5 (0.5)	.58
Hb 7.9–7.0 g/dL	1.5 (0.96)	1.6 (1.1)	1.4 (0.6)	1.8 (1.6)	.96
Hb <7.0 g/dL	2.2 (1.4)	2.1 (1.4)	2.5 (1.6)	2.1 (1.1)	.06

Note: Sample includes only patients receiving a transfusion and is restricted to patients with seven or less transfusions during hospitalization.

^a p‐values represent Kruskal–Wallis test comparing the average number of RBC units transfused across Hb level (rows) by racial group.
