Kaplan-Meier curve of disease-free survival (DFS) () and overall survival (OS) () stratified by positive nodes. Median DFS and OS for patients without positive nodes were 20.3 months (95% CI 12.4–28.8) and 67 months (95% CI 53–119.3), respectively, versus 14.4 (95% CI 5.8–28.7) and 64.7 months (95% CI 37.9–70.9), respectively, for those with 1 to 3 positive lymph nodes versus 10.4 (95% CI 3.6–16.6) and 21.7 months (95% CI 14–77.2), respectively, for patients 4 or more positive lymph nodes.
