FIGURE 1 Kaplan-Meier curves for survival. Kaplan-Meier curves for disease-free survival (panel A) and for overall survival (panel B) by gefitinib/erlotinib therapy. G/E denotes gefitinib/erlotinib. *Hazard ratios were calculated with the use of a Cox proportional hazards model, with the type of surgery, stage, cisplatin chemotherapy, and sex as covariates and gefitinib/erlotinib therapy as time-dependent factor; Cox proportional hazards model with gefitinib/erlotinib therapy as time-dependent factor. With respect to the disease-free survival and overall survival, results of a log-rank test, p = (panel A) and p = (panel B).
