Crucially, PFS was analyzed with censoring at the time of local therapy, whereas EFS counted initiation of subsequent anti-tumor therapy, including local therapy, as an event; under this definition, the between-group difference in EFS did not reach statistical significance (HR 0.64; 95% CI 0.40–1.02; nominal P = 0.0598).
