3 Fig 2 Percentage of patients with a nodal upstaging based on the number of lymph nodes assessed. (N = node.) The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2017 The Society of Thoracic Surgeons Terms and Conditions

4 Fig 3 Multivariable analysis of the optimum number of lymph nodes needed to be assessed for node-positive patients being correctly identified. Adjusted for year of diagnosis, age, sex, race, insurance status, comorbidity index, facility type, facility volume, histologic finding, and stage. Two-point increments are shown for clarity.
