Pairwise comparisons significant for the treatment categories were as follows for SD, treatment category 2 versus treatment category 3 (P = .03), treatment category 3 versus treatment category 4 (P = .002), treatment category 3 versus treatment category 5 (P = .006); and for URD, treatment category 2 versus treatment category 4 (P = .04), treatment category 2 versus treatment category 5 (P = .0001).
RR indicates relative risk; KPS, Karnofsky performance score; MDS, myelodysplastic syndrome; D, donor; R, recipient; M, male; F, female; N, negative; P, positive; CSA, cyclosporine; MTX, methotrexate; and MA, myeloablative.
