Fig. 3From: Development and validation of a risk prediction model for overall survival in patients with nasopharyngeal carcinoma: a prospective cohort study in ChinaThe calibration curves for predicting patient OS at 1,3 and 5Â years in the training cohort and at 1,3 and 5Â years in the validation cohort. Nomogram model-predicted OS is plotted on the x-axis; actual OS is plotted on the y-axis. Closer alignment with the diagonal with the diagonal line represents a better estimationBack to article page
