Fig. 2

The risk score, survival time, and gene value distribution of high and low risk samples for the training set (a) and validation set (b). The figures from top to bottom are the risk score distribution, scatter plot of survival time distribution, box plot of survival time distribution, and gene expression heat map, respectively. Red represents the high risk samples, while the blue represents the low risk samples. The color changes of red-white-blue represent the gene expression value from high to low. The genes with higher expression values in low risk samples, and lower expression values in high risk samples may induce a higher risk score
