  2. a The numbers indicate the frequencies of yes/no/don't know
  3. b The numbers indicate the frequencies of correct/incorrect/don't know
  4. c The Kappa statistics (κ) was originally unavailable due to non-square contingency tables. Cases with a sample weight of 0.1 were added to recover the estimate
  5. d N = 37 due to one missing answer
