Establishment of the prognostic nomogram for 5-year survival. a Nomogram for predicting survival probabilities. Each clinical characteristic is shown with its corresponding score. PON1 was used as a novel liver-specific variable in the nomogram. The C-index of the nomogram was 0.714. b Calibration plot of OS at 5 years to visualize the difference between true values and predicted values. c ROC curves of AJCC tumor stage (0.5349), serum AFP (0.4888), and tumor T stage (0.5656) for predicting 5-year survival are shown for comparison
