In the univariable and multivariable analyses, stage was an independent prognostic factor for progression-free survival, locoregional recurrence-free survival, and distant metastasis-free survival in the intention-to-treat population and the per-protocol population, marginal significance for overall survival in the intention-to-treat population (Table 2 , Supplementary Table 5 ).
