Classification and regression tree. Classification and regression decision tree (CART) analysis was performed to verify the prognostic factors. Square boxes indicate subsets of patients defined by the sequential splitting process. Finally, the CART analysis identified three risk groups: Group A (nodal SUVmax ≤7.49 and HPV positive), Group B (nodal SUVmax ≤7.49 and HPV negative), and Group C (nodal SUVmax > 7.49). Cox proportional hazard model calculated hazard ratios (HRs) of Group B (HR, 3.56; p = 0.006) and Group C (HR, 10.13; p < 0.001), compared to Group A (HR, 1.00)
