This analysis of gene expression ranks 36 genes on the basis of their predictive power (univariate z score), with a negative score associated with longer overall survival and a positive score associated with shorter overall survival. The dashed lines represent an absolute univariate z score of ± 1.5. The prediction model is based on the weighted expression of six genes in the equation shown. (N Engl J Med, 350:1828–37, 2004.)
