Figure 5. Assess the ability of risk scores to differentiate patients in high and low risk group. (A, B) PCA and tSNE assessed the ability of risk scores to distinguish between high and low risk groups of patients in the TCGA cohorts. (C, D) PCA and tSNE assessed the ability of risk scores to distinguish between high and low risk groups of patients in the GEOcohorts. PCA: principal components analysis; tSNE: t-distributed stochastic neighbor embedding.
