*This model was applied to patients with low or int-1 MDS according to the IPSS.1 The characteristics were identified by multivariate analysis in 856 patients from MDACC. Each characteristic was assigned a specific score shown in the right column. In this analysis, only diploid and 5q– were favorable cytogenetically; all others were considered as unfavorable cytogenetics. (Adapted from Garcia-Manero et al., 2008.8 )
