The classification comparison of IGSA, HCBP (hierarchical clustering based on pathways) and HCBG (hierarchical clustering based on genes) in ovarian cancer datasets (TCGA batch 9).

<p>A shows the survival time curves of three classes obtained by IGSA (p value of 0.0362). B shows the survival analysis of three classes obtained by HCBP (p value of 0.187). C shows the survival time curves of three classes obtained by HCBG (p value of only 0.240). D shows the survival time curves of two classes (class 1 and class 2,3) obtained by IGSA (p value of 0.0362). The p values in both A and D are significant compared with HCBP and HCBG.
