Fig 1 Kaplan-Meier freedom from local recurrence, freedom from distant metastasis, and survival curves for 107 patients with complete resection of N1 non–small cell lung carcinoma. No patient received adjuvant or neoadjuvant therapy. The Annals of Thoracic Surgery 1999 68, 1171-1176DOI: (10.1016/S0003-4975(99)00678-5)
Fig 2 Classification and regression tree analyses were used to separate patients into risk groups according to (top) freedom from local recurrence, (middle) freedom from distant metastasis, and (bottom) survival.

Fig 3 Freedom from local recurrence (top), freedom from distant metastasis (middle), and overall survival (bottom) rates for patients at low, intermediate, and high risk for local recurrence were well separated, supporting the efficacy of classification and regression tree analyses in determining risk groups.
