Readability and testing with readers

This branch covers assessing whether a document can be read and used, divided by assessment method: readability formulas and testing with intended readers. It leaves plain-language drafting, health literacy, readable layout and document-specific testing of trial-results summaries to neighbouring branches.

• Readability formulas and what a score can tell — measured features, score limits, grade levels, practical recommendations, comparisons with reader performance and the relationship between grade level and cohesion
• Testing with real readers — performance and feedback, participants and interviews, iterative procedures, sample sizes, pictorial information, assessment criteria and feedback after publication
