Figure 1.
A total of 2433 patients met the enrollment criteria. The population were first divided into 2×3 subgroups by BMI levels and weight loss status, and analyzed in the multiple-adjusted Cox model. Stratified analysis by BMI levels was further conducted to determine the impact of high weight loss during treatment for NPC patients with different BMI levels. Footnote: d, death; n, number of patients.

Adjusted hazard ratios of high weight loss for survival in patients stratified by BMI levels.
Hazard ratios of high weight loss for overall survival (OS) and disease-specific survival (DSS) in NPC patients receiving radical radiotherapy, stratified by BMI levels. HR was adjusted for age, sex, UICC T stage, UICC N stage, and treatment; 95% CIs were shown.
