In the article by Baurmann et al entitled “Kinetics of the Graft-Versus-Leukemia Response After Donor Leukocyte Infusions for Relapsed Chronic Myeloid Leukemia After Allogeneic Bone Marrow Transplantation,” which appeared in the November 15, 1998 issue, pages 3582-3590, a correction should be noted for the legend to figure 4. The symbol for mixed recipient/donor DNA Chimerish should be a square with a star inside, and not a blank square.
