Fig. 5

Calibration plot for validation cohort (n = 114). The nomogram makes a pessimistic prediction for the external validation cohort (the solid line is generally above the dotted line). Furthermore, as time passes, the predictive ability decreases (i.e., the calibration deviates from the x = y line), which may be due to the poor prognosis (median survival of approximately 6 months). CI, confidence interval; OS, overall survival.
