Note: 6 children are missing Mullen scores (3 ASD, 1 HR-noASD, 2 LR); 1 ASD child is missing an ADOS severity score. See text for explanations.

Means with different superscripts differ at p <.05 or better; see text.

ASD = toddlers with a later ASD diagnosis

HR-noASD = high risk toddlers without a later ASD diagnosis

LR = low risk toddlers
