Spearman’s correlation coefficient graph. The correlation between the risk scores of the prognostic models and immunohistochemical scores of p53 (A) and Ki-67 (B). The distribution of each variable is shown on the diagonal line, including p53/Ki-67 H-Score, Integrated_PFS_riskScore, Integrated_OS_riskScore, Conventional_PFS_riskScore, Conventional_OS_riskScore, Inter-tumor_PFS_riskScore, and Inter-tumor_OS_riskScore. The part below the diagonal line shows the scatterplots and fitting curves of the two variables. The part above the diagonal line shows Spearman’s correlation values of the two variables and the corresponding significance levels: *** represents p < 0.001
