All models included random effects for intercepts and Age and Vocabulary at baseline as covariates. Model 1 is the null mixed model (i.e., intercepts and covariates only); Model 2 is the mixed model with main effects; and Model 3 is the mixed model with main effects and interactions. Coefficients and standard errors (in parentheses). ** p < 0.05, *** p < 0.01.
