Figure 3 Time-dependent receiver operating characteristic curves for the seventh edition of the American Joint Committee on Cancer TNM staging system and modified staging system with the revised N categories for (A) 3-year and (B) 5-year overall survival. Decision curve analyses of the seventh edition of the American Joint Committee on Cancer TNM staging system and modified staging system with the revised N categories for (C) 3-year and (D) 5-year overall survival. AUC, area under the curve; CI, confidence interval. Journal of Thoracic Oncology , DOI: ( /j.jtho ) Copyright © 2016 International Association for the Study of Lung Cancer Terms and Conditions
