Figure 1. Impact of the Incremental Benefit of radiotherapy (RT) for RT Decision-Making*.

* The questionnaire stated that RT can prevent cancer recurrence, but may have some negative effects.

We then asked “Thinking about what is important to you, how significant would the benefit of radiation need to be for you to decide to receive radiation therapy?” 13 participants who had missing value, or responded as “don’t know/unsure” or “refuse to answer” were excluded in this figure.
