*
Missing data were multiply imputed at baseline for one participant assigned to treatment as usual (TAU), and at endpoint for six assigned to TAU and eight assigned to Preschool Autism Communication Trial (PACT).
†
Unavailable at baseline because participants were generally too young; standard scores normed to population mean=100 and SD=15.
