Kaplan-Meier curves of progression-free survival (PFS3; A,C,E) and overall survival (OS3; B,D,F) with the third-line treatment. a, b Analyses of the whole study cohort showed that patients receiving chemotherapy and those receiving erlotinib had similar PFS3 (MST of PFS3: 2.9 vs. 3.1 months, log-rank p = 0.8945) and OS3 (MST of OS3: 8.9 vs. 7.9 months, log-rank p = 0.4956). c, d Analyses of the patients receiving chemotherapy showed that patients receiving platinum-based doublet had a similar PFS3 and a trend for better OS3 as compared with those receiving chemotherapy without platinum (MST of PFS3: 3.2 vs. 2.8 months, log-rank p = 0.5760; MST of OS3: 10.6 vs. 7.5 months, log-rank p = 0.0545). e, f Analyses of the patients receiving chemotherapy showed that patients receiving pemetrexed had a similar PFS3 and a trend for better OS3 as compared with those receiving chemotherapy without pemetrexed (MST of PFS3: 2.9 vs. 3.0 months, log-rank p = 0.2045; MST of OS3: undefined vs. 7.7 months, log-rank p = 0.0795). Abbreviation: MST = median survival time
