Kaplan–Meier survival curves for high- and low-risk HNSCC patients. The high- and low risk groups are defined by the median of A clinical score, B main effect score, C G × G interaction score, D epigenetic score, and E ATHENA score. F Discriminative ability of the ATHENA score is illustrated by Kaplan–Meier survival curves of six groups, defined by quantiles at 20%, 40%, 60%, 80% and 90% of ATHENA score
