The constructed radiomic nomogram M_p+RRS (A) integrating the pathologic tumor stage (T stage) with the RRS_HPV+. RRS_HPV+ has more effect on DFS than the T stage, as indicated by a wider range of the total points. Calibration curves have good agreement between predicted and actual survival probability on S_T (B) and S_V+S_CCF (C). Decision curve on S_T+S_V+S_CCF (D) compared the clinical usefulness of radiomic nomogram M_p+RRS (black dash line) in DFS prediction against the pathologic staging nomogram M_p (red dash line) and the clinical nomogram M_c (green dash line).
