Fig. 5From: Prognostic significance of AKR1C4 and the advantage of combining EBV DNA to stratify patients at high risk of locoregional recurrence of nasopharyngeal carcinomaNomogram predicting 3-year and 5-year survival in NPC patients. A The nomogram consists of T stage, EBV DNA, and AKR1C4 level. B Calibration curve for predicting local recurrence at 5Â years. The actual 5-year LRFS is plotted on the Y-axis, and the nomogram-predicted probability of local recurrence is plotted on the X-axis.
