Immune infiltration between the high- and low-risk groups. A The relative infiltration ratio of immune cells in all OSCC patients. B The violin diagram of immune cells of the difference between the high- and low-risk groups. The x-axis is the 21 immune cells and the y-axis is the infiltration ration of immune cells. We used the wilcoxn method to calculate the p value. (ns: p > 0.05, *: p <  = 0.05, **: p <  = 0.01, ***: p <  = 0.001, ****: p <  = 0.0001). C The box graph of differentially expressed immune cells between the high- and low-risk groups. The x-axis is the high- and low-risk groups. The y-axis is the infiltration ratio of immune cells and p value is calculated by the wilcoxn method. D The correlation matrix of 22 immune cells. The orange is positive correlation and the blue represents negative correlation. The greatness of the correlation is positively related to the darkness of the color. E The chord diagram of Risk Score and 5 immune checkpoints. The width of the connecting lines represent the strength of the correlation. F The violin diagram of the difference of expression of the checkpoints between the high- and low-risk groups. The red is high-risk group and the blue is low-risk group. The y-axis is the expression of the checkpoints, and p value is calculated by the wilcoxn method
