Statistical analysis
toxicity
The primary endpoint of this trial was the change of weight during CCRT. We assumed that the change of weight could be reduced from −5.0% according to previous studiesA descriptive statistical analysis of baseline characterization and toxicity was performed. For all outcome measures, differences among groups were tested using one‐way ANOVA or Chi‐square test. Kaplan–Meier method was used to estimate the survival rates. We report the corresponding symmetric 95% confidence intervals (CIs).
