  1. F test were used to compare means across conditions and chi square tests were used to compare proportions across the conditions. Cells do not always equal 100% due to rounding
  2. M = Mean, SD = Standard Deviation, NA = not applicable due to small cell count
  3. an (%) unless otherwise noted
  4. bDue to small cell count, reported χ2 statistic represents Caucasian compared to all other races
  5. cHealth literacy was assessed using the validated Newest Vital Sign
