Fig. 4: EFS from definitive surgery in patients with stage III N2 or non-N2 NSCLC by pCR status.
a–d, EFS from surgery in patients with N2 NSCLC by pCR status (a), patients with non-N2 NSCLC by pCR status (b), patients with N2 NSCLC without pCR who received at least one dose of adjuvant treatment (c) and patients with non-N2 NSCLC without pCR who received at least one dose of adjuvant treatment (d). The superscript letter ‘a’ indicates that EFS from surgery included only patients with definitive surgery and with pCR status available. The ‘Without pCR’ subgroup included patients with pCR negatively assessed. The superscript letter ‘b’ indicates that HRs were not calculated for subgroups with less than ten responders in either treatment arm. The HRs and the two-sided 95% CIs for comparisons of EFS between the treatment arms were estimated using an unstratified Cox proportional hazards model using the randomized arm as a single covariate; NC, not calculated.
