  1. SAM = suitability assessment of materials, CR = cardiac rehabilitation.
  2. † scored on a 5-point Likert scale from 1 (low quality) to 5 (high quality).
  3. §scores out of a possible 80 where higher scores represent higher quality.
  4. ‡ scores out of a possible 100, higher scores represent greater ease of understanding.
  5. * scores out of a possible 100, higher scores represent higher personal interest.
  6. ** sores out of a possible 100, higher scores represent greater suitability.
  7. p = probability of test statistic for difference between the combined new leaflets and the existing CR leaflets
