  1. aAdjusted for post-stratification weights
  2. bAOR (Adjusted Odds Ratio) greater than 1 means the participant characteristic is positively associated with willingness to give blanket consent, and less than 1 means the characteristic is negatively associated with willingness to give blanket consent
  3. cRange is 1 to 7 (higher is more conservative)
  4. dRange is 1 to 5 (higher is more worried)
  5. eRAQ is the 11 item Research Attitudes Questionnaire, assessing attitudes toward medical research. Range is 11–66 (a higher score corresponds to more positive attitudes)
