Nomogram integrating the four-bacteria signature and clinical factors. A Establishment of a nomogram integrating the four-bacterial signature, N stage, and plasma EBV-DNA load to predict disease-free survival (DFS) in the training cohort. B Calibration curves of the nomogram to predict DFS at 5 years in the training cohort. C Calibration curves of the nomogram to predict DFS at 5 years in the internal validation cohort. D Calibration curves of the nomogram to predict DFS at 5 years in the external validation cohort. E Receiver operating characteristic (ROC) curves of the established nomogram to evaluate DFS of NPC patients in the training, internal, and external validation cohorts
