Fig 1 Overall survival curves for patients with stage I non-small cell lung cancer (group 1, dotted line; group 2, thin solid line; group 3, thick solid line). Survival curves were plotted using Kaplan-Meier methods. Statistically significant differences in survival between groups were analyzed by the log-rank test.
