Nomogram establishment
RECURRENCE
The risk prediction model using the nomogram was based on the combined model (Fig. Construct a nomogram based on the combined model and add the points of each variable to obtain the total points. The total points correspond to the risk probability of early postoperative recurrence (Risk), which can be visualized Readout of the nomogram predicts a patient’s risk probability of recurrence within one year after surgeryNomogram risk prediction model calibration curve.
