Fig. 3: A nomogram prediction model was constructed based on the expression of BART22 in NPC.

A The nasopharyngeal carcinoma survival nomogram. (To use the nomogram, an individual patient’s value is located on each variable axis, and a line is drawn upward to determine the number of points received for each variable value. The sum of these numbers is located on the Total Points axis, and a line is drawn downward to the survival axes to determine the likelihood of 5-, 6- or 7-year survival). Risk of survival time can be determined by assigning points for each variable by drawing a line upward from the corresponding variable to the points line, summing the points, and identifying the prediction of survival time associated with the total points line. EBV-miR-BART-22, the level of tissue EBV-miR-BART-22 before treatment. B Calibration plots for predicting for NPC OS at 5-, 6-, and 7-year. The blue dotted line indicates the ideal nomogram; blue X indicates the bootstrap-corrected estimates; vertical bars indicate the 95% CIs. C ROC curves of the 5-, 6-, and 7-year nomograms of NPC patients. The red bars represent new nomogram-predicted OS, whereas the black bars represent TNM stage predicted OS.
