Figure 1. — Comparison of survival rate between icotinib and pemetrexed in treatment of lung adenocarcinoma. The results of Kaplan-Meier test for survival analysis showed that the median survival time of patients was 16 months in the icotinib group, higher than that in the pemetrexed group (10 months), with a statistically significant difference (P<0.05). The 1-year survival rate was higher in the icotinib group than that in the pemetrexed group (P<0.05). There were no differences in 2- and 3-year survival rates between the two groups (P>0.05).
