The predictive performance of the nomogram. (a) Validity of the predictive performance of the nomogram and MELD score in estimating the risk of mortality in the training cohort. (b) Validity of the predictive performance of the nomogram and MELD score estimating the risk of mortality in the validation cohort. Nomogram or MELD score predicted probability of overall survival is plotted on the x-axis, while actual overall survival is plotted on the y-axis
