  1. This table shows the detailed statistics from the ANOVA-investigated differences between classes in symptom severity at 36 months as measured by the ADOS, ADI-R, and SCQ. When differences were significant, post hoc Tukey’s tests for multiple comparisons were performed for paired comparisons of classes. Differences were considered significant for p < 0.05 (marked as “*”)
  2. ANOVA analysis of variance, Class 1 decreasing adaptive behaviour, Class 2 average/stable adaptive behaviour, Class 3 recovering adaptive behavior, dof degrees of freedom, ADOS Autism Diagnostic Observation Schedule, CSS Calibrated Severity Score, ADI-R Autism Diagnostic Interview-Revised, SCQ Social Communication Questionnaire
