The calibration curve for predicting patients without recurrence at A 36-month, B 60-month and C 120-monthin the derivation cohort. Nomogram-predicted probability of overall without recurrence is plotted on the x-axis, actual overall without recurrence is plotted on the y-axis. The grey line represents a perfect fit between the nomogram predicted probability and the observed probability. The blue line represents performance of the present nomogram. Closer distances between the two lines represent higher prediction accuracy
