Fig. 2From: Development and validation of a nomogram for predicting the survival of patients with non-metastatic nasopharyngeal carcinoma after curative treatmentThe calibration curve for predicting overall survival (OS) of patients with non-metastatic NPC in the internal validation set (a) and intensity-modulated radiation therapy (IMRT) cohort (b). The nomogram-predicted probability of OS is plotted on the x-axis; the actual OS is plotted on the y-axisBack to article page
