Characteristics of prognostic gene signatures. a, c K–M curves for OS (a) and RFS (c) in the high- and low-risk groups when stratified by the autophagy-related signatures. b, d ROC curve of risk score at 1,3,5 years for OS (b) and RFS (d) respectively. e, f Distribution of OS-related risk score and RFS-related risk score, the black dotted line is the optimal cut-off value for dividing patients into low- and high-risk groups. g, h Distribution of patient survival time, and status. i, j Heatmap of autophagy-related gene expression profiles in the prognostic signature of CC
