aThe Overall Group Comparison serves as an omnibus test comparing the means between the four groups to determine whether group means differ based on a mixed model with repeated measures. Model covariates included the difference between the child’s actual age at the visit from the scheduled visit age (6 and12 months). Other covariates included site and mother’s education. Two-sided at significance level of .05
bPost hoc comparisons with step-up Bonferroni correction. Two-sided at significance level of .05
