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