Fig. 4: MCT attribute preferences by patient characteristics.

“Base” is the base coefficient, meaning the reference categories for each characteristic. Each characteristic was tested in model refinement and non-significant interaction terms were removed for parsimony. All enter as binary variables (except for cancer knowledge and experience, “Experience”), with the reference category shown in parentheses. “Experience” here is a combination of: the individual has undergone cancer screening (versus has not), the individual has previously had cancer (versus has not), and the individual can identify 8 out of 16 cancer symptoms.
