Figure 2. Kaplan-Meier plot of overall survival.

Figure 2

Overall survival was defined as the duration from date of randomization to date of death as the result of any cause. Censoring was done on the date the patient was last known to be alive, for patients who were still alive at the date of the last follow-up visit. Confidence intervals are based on the binomial distribution. Kaplan-Meier analyses were performed for the 2-year survival rate. Abbreviations: CI=confidence interval; NE=not evaluable; PC=pemetrexed-cisplatin; PCb=pemetrexed-carboplatin; * censured patients
