Bal, V. H., Fok, M., Lord, C., Smith, I. M., Mirenda, P., Szatmari, P., … & Bennett, T. (2020). Predictors of longer‐term development of expressive language in two independent longitudinal cohorts of language‐delayed preschoolers with Autism Spectrum Disorder. Journal of Child Psychology and Psychiatry, 61(7), 826-835.
