Fig. 1 Markov model describing health states after treatment for early-stage non–small-cell lung cancer. 3D-CRT = three-dimensional conformal radiation therapy; NED = no evidence of disease; SBRT = stereotactic body radiotherapy; RFA = radiofrequency ablation.

Fig. 2 Acceptability curve. This curve represents the proportion of trials drawn on a hypothetical distribution of unknown parameters that result in an incremental cost-effectiveness ratio for stereotactic body radiotherapy (SBRT) less than the societal willingness to pay. Varied parameters include efficacy of three-dimensional conformal radiation therapy (3D-CRT), SBRT, and radiofrequency ablation (RFA), as well as utility values of no evidence of disease (NED) and recurrence health states. QALY = quality-adjusted life-year. International Journal of Radiation Oncology • Biology • Physics , e767-e774DOI: ( /j.ijrobp ) Copyright © 2011 Elsevier Inc. Terms and Conditions
