The number of networks (A) and patients (B) using SBRT over time
Abbreviations: SBRT, stereotactic body radiation therapy
*Includes both existing and new SBRT adopters since 2007 is the first year of the study.
Since 2007 was the first year of the study period, we could not distinguish new and existing SBRT users (*). In subsequent years, we distinguished networks that were existing users of SBRT (black) from new adopters of SBRT (gray). (A) The x-axis represents the number of networks using SBRT over time. (B) The x-axis represents the number of patients who received SBRT within networks performing SBRT.
