The performance of immune-based risk models for DFS. (a) The rank of relative importance of Gal-9 on TC, CD4, and PD-1 for DFS according to the random forest. The F1-score and AUC of CD4, PD-1, Gal-9, and the combination of the three proteins for 1 y- (b), 3-y (c), and 5-y DFS (d). The heights of the columns represent the average of 100 testing groups, and vertical lines represent the standard error of mean (SEM) of 100 testing groups. ***P < 0.001

Abbreviations: DFS, disease-free survival; HR, hazard ratio; TNM, tumor, nodes, and metastasis; TC, tumor cell; CD4, cluster of differentiation 4; PD-1, programmed death-1; Gal-9, galectin-9; AUC, areas under time-dependent receiver-operating characteristic curves.
