CMV indicates cytomegalovirus; SE, standard error; LR, leukoreduced.
Period 1: April 1994-November 1996, N = 360 patients.
Period 2: December 1996-February 2000, N = 447 patients.
Table reports units of product (ie, one unit from one donor). For pooled platelets, one “unit” represents pool of 6 random concentrates. CMV status of pool is positive if one unit in pool is positive or unknown.
