Cost-Effectiveness of Alternative Management Strategies for Patients with Solitary Pulmonary Nodules

Appendix (Figure 4). Survival curves for patients with pathologically staged lung cancer (T1N0M0), pathologically staged regional
lung cancer (any T N1–3 M0), and distant lung cancer (any T any N M1) are from the linked Medicare claims–Surveillance, Epidemiology
and End Results ( ) tumor registry. Modeled survival was based on Markov transition probabilities. For patients with local
and regional lung cancer, modeled survival closely approximated observed survival.
