  • Bold=statistically significant findings at p<0.05.

  • *Adjusted for child age at follow-up in months, child sex, birth weight, maternal ethnicity, family income. All covariates were measured at baseline except child age which was at follow-up.

  • †Each row shows results from three separate models.

  • ‡An ITC screen is positive if there is concern for speech delay and/or other communication delays.
