Figure 1. Identification of differentially expressed genes using our approach and traditional methods.

The four genes that were not consistently identified using the traditional method and our method are listed. The horizontal axis represents samples, and the vertical axis represents gene expression. Samples on the left of the red line are from the poor prognosis group, and those on the right are from the good prognosis group. Pr and Pl represent the p value obtained by randomization and the Limma algorithm, respectively.
