Figure 1.

Shown are Kaplan-Meier curves for PFS. The tick marks indicate censored data, and the dashed vertical lines indicate the times of landmark analyses of PFS.

PFS in patients (A) with or (B) without^a stage IIIA-N2 NSCLC.

CI, confidence interval; DCO, data cut-off; HR, hazard ratio; NE, not estimable; NR, not reached; NSCLC, non-small-cell lung cancer; PFS, progression-free survival.

^aPatients with all other stages (including stages IIIA-N0/N1 and IIIB). DCO = 13 February 2017 (DCO for the primary analysis of PFS): median follow-up of 14.5 months (range: 0.2-29.9 months).
