Figure 5. Survival, expression, and correlation analysis of the hub-genes in CRC. (A–D) Expression analysis for four genes (MMP3, MMP9, TIMP1 and VEGFA), red represents as Tumor, gray represents as Normal. (E) The correlation analysis for four genes (MMP3, MMP9, TIMP1 and VEGFA). (F) The KM survival plots for prognostic model which consist of four genes (MMP3, MMP9, TIMP1 and VEGFA). (G) The ROC curve analysis predicted this prognostic model at 1-, 3-, and 5-year survival rates.
