Summary of multivariate analysis of prognostic factors in 749 patients with nasopharyngeal carcinoma.

Abbreviations: CI  =  confidence interval; HR =  hazard ratio; CLN  =  cervical lymph nodes; NS  =  not significant; SCLN = Supraclavicular lymph node.
*P values were calculated using an adjusted Cox proportional-hazards model. The following known important prognostic variables were included in the Cox proportional hazards model: age (≤50 vs. >50 years), gender, T-classification, chemotherapy (yes vs. no), bilateral CLN metastasis (yes vs. no), dimension of CLN metastases (≤6 vs. >6 cm), CLN location (with SCLN vs. without SCLN) and RLN metastasis (yes vs. no).
