All presented data are mean ± SD.
Dx, diagnosis; Tx, transfusion.
Pretransfusion Hb levels within 18 hours of Tx, and Hb increments within 18-hour period after Tx for the initial period and between the 18- and 36-hour period after Tx for 24-hour increment. Tx recipients of gamma irradiated RBCs compared with unirradiated RBCs had smaller Hb increments in patients with and without an oncologic Dx. All P values <.001 by Student t tests.
