Note: NVIQ = Nonverbal Intelligence Quotient; DAS = Differential Abilities Scales (Preschool or School Age); WASI = Wechsler Abbreviated Scale of Intelligence. Sample size differed for age 3 ADOS (n = 82).
At the age 19 visit, one individual was 213 months of age and therefore within the age range to receive a standard score on the DAS.

At age 19, n=30 (36%) of children had single words or no words according to the ADOS Overall Level of Non-Echoed Language code.
