  1. 1. The percentage of cases that responded equates to response rate (AAPOR RR1)
  2. 2. Risk ratios from multivariable models predicting survey response that include design features and adjust for time since diagnosis, sex, age, race, ethnicity, geography, cancer site, and cancer stage at diagnosis. In these models, none of the demographic or cancer variables significantly predicted response
  3. 3. When conducting the model using a single reference group to compare all four mode-brochure combinations simultaneously, the adjusted risk ratios were as follows: Paper, no brochure: Ref.; Paper, brochure: RR = 0.98 (95% CI: 0.76, 1.27); Web, no brochure: RR = 0.83 (95% CI: 0.62, 1.10); Web, brochure: RR = 0.91 (95% CI: 0.70, 1.18)
