Selected online materials available for AF education, and their readability levels, as assessed by the FKGL and SMOG measures
Websites of selected medical professional societies, major academic medical centres and Internet-based medical references were identified through an Internet-based search using widely-accessible search engines. FKGL and SMOG provide grade-level estimates. Dale–Chall Readability is a scaled measure for evaluating the expected reading grade level for text comprehension; for example, a score of 7.0–7.9 indicates reading grade level 9–10, and 8.0–8.9 indicates grade level 11–12. Estimated Lexile Measure is an internationally-employed measure for gauging reading level, with higher scores corresponding to greater text complexity. FKGL = Flesch-Kincaid Grade Level; (for consistency) SMOG = Simple Measure of Gobbledygook score.
