KM analysis for high and low risk score groups in training set and characteristics of samples in the two groups. A KM plot for high and low risk score groups in training set: x-axis referred to living time (months), y-axis referred to the survival probability (up) and risk score group (down), number table in the lower part of the plot referred to number of patients at risk. B Scatter plots for the survival characteristics of patients with increasing risk score and heatmap for the expression of final genes in patients with increasing risk score: the vertical dashed lines divided the samples into high and low score group, left side referred to high score group, right side referred to low score group
