FIGURE 3.

Intelligence quotient (IQ) (ELC) by age groupings: age bins and frequency histograms for infants with ASD and TD outcomes. Data from infants with at least three or more assessments on the Mullen, such that at least two of the assessments fall within the pre‐defined age bins. (a) Age bins (6, 12, 18, 24, 30, and 36 ± 1 months). (b) For each of the age bins in (a), frequency and probability density function (PDFs) are shown. ASD, Autism Spectrum Disorder; TD, typically developing. The width of the bars is 15, equal to the SD of the Early Learning Composite (ELC) standard score (mean 100)
