There were no concrete findings - these were informal tests in a field where concrete findings are nigh-on impossible. The website is a mix of marketing and longform, advertising dyslexia services. Often it's read by the parent of a dyslexic so there's two audiences to address. Of the dyslexics we tested with, all found the fonts hurt readability and they were seeing individual letters (instead of words) more than they were with a standard font (Source Sans Pro). The parents we also tested found the 'Dyslexic' fonts very hard to read. So for our small sample of children it didn't help, and in this situation wasn't worth pursuing. Most of these children IIRC find a coloured overlay is all they need to read acceptably; colour and contrast is another thing I'd have liked to test but there's only so much you can subject children (who aren't your own) to!
