Internal validation of the nomogram used to predict OS and PFS in patients with upper aerodigestive tract nasal-type extranodal natural killer/T-cell lymphoma. Discrimination and Calibration: Calibration plot for predicting 5-year OS rate (a) and 5-year PFS rate (b). The areas under the receiver operating characteristic curve are 0.697 for 5-year OS rate (c) and 0.634 for 5-year PFS rate (d). The nomogram-predicted survival is plotted on the X axis; the actual survival is plotted on the Y axis. AUC area under the curve
