The mean readability of OCs was at grade level 13.8 ± 1.3 (range = 10 17), whereas the average text point size was 11.0 ± 1.4 (range = 6 16).
The mean readability score was 14.3±1.7 (mean±SD).
The mean readability score and SD were calculated for each article.
One-sample t tests were used to compare the mean readability scores of the AD forms as determined by the Flesch-Kincaid readability scale with the recommended readability level of the National Work Group on Literacy and Health and the average reading skill level of US adults.
The mean Flesch readability score was 75, representing "fairly easy to read", all leaflets scored in the superior category for suitability and were reported to be easy to understand, useful and motivating by persons with CHD risk factors.
For the Flesch-Kincaid Grade Level and Dale-Chall readability formulas, a higher score means a more difficult text, while the Flesch-Kincaid Reading Ease score is the opposite.
The graphs only plot mean values for better readability.
The average readability of leaflets from ADA was 8th grade (Mean-8.4, SD-0.1); commercial industry was 7th grade (Mean-7.1, SD -1.7); and those from the State/Territory Health Departments was 6th grade (Mean-6.3, SD-1.9).
The term 'average' was used in place of 'least square means' throughout this manuscript to improve readability.
The primary outcomes are the frequency distribution of overall SAM readability category (superior, adequate, or not suitable) and mean SMOG reading grade level.
For example, with the Flesch-Kincaid readability scale, the 62 AD forms had a mean score of grade level 11.9 (SD, 2.6) and the median score was grade level 11.6 (range, 7.6-19.0).
