Unstandardized Beta coefficients (ß), significance level (Sig.) and confidence interval for Beta (95%) for each factor entered in the regression models with measures of the Social Responsiveness Scale as outcome. For each model, cognitive factors were entered in a first step (BRIEF Global Executive Composite (BRIEF-GEC), Age, Motor Free Visual Perceptual Test (MVPT-3), and Verbal IQ (VIQ)), followed by group membership in a second step (TS and Controls). Each model's R² and p values are indicated.
