Model 5 fixed effects for 3-year-olds, with CV letters as the referent category. The vowel contrast was significant; no standardized effect size is printed, and the article does not report this contrast for 5-year-olds.

"In addition, students had a higher probability of correctly writing vowels, predicted probability = .04, t(3594) = 2.05, p < .001, compared with CV letters."
