ADI (The Autism Diagnostic Interview – Revised); ADOS (The Autism Diagnostic Observation Schedule), values used were calibrated severity scores; SRS (Social Responsiveness Scale), value was the total t-Score; CDI words understood (MacArthur-Bates Communicative Development Inventory) was derived by summing words understood only and words understood and spoken; MSEL (Mullen Scales of Early Learning), MSEL Verbal combined verbal subscales (receptive and expressive language), MSEL Non-Verbal combined two non-verbal subscales (visual reception and fine motor), MSEL ELC (Early Learning Composite) combined those four subscales. Where both values were normally distributed, parametric Pearson’s r is reported (shaded) otherwise where one or both variables were not normally distributed, values are Kendall’s tau (unshaded). All values are uncorrected for multiple comparisons. ^∗p < = 0.01 level; bold values indicate where correlations remained significant after correction for multiple comparison (p < = 0.004). ^$Accounting for 15 mo.
