Categorical variable, strong = 1, non-strong (adequate and weak) = 0.

b

Time interval between postintervention and follow-up.

c

Mean age of participants at last assessment.

d

Categorical variable, EIBI = 1, non-EIBI (ESDM and other interventions) = 0.

Based on the result of sensitivity analysis, Magiati et al. (20) was removed from the meta-regression analyses.

ASD SS, ASD symptom severity; Coeff, unstandardized meta-regression coefficient; Composite, Vineland adaptive composite score; DLS, Daily living skills; Pre, preintervention.

p < 0.05.

ASD symptom severity - Approaches: Adj R2 = 64.19%. Vineland adaptive composite score - Total treatment hours: Adj R2 = 78.06%. Vineland social adaptive score - Total treatment hours: Adj R2 = 100.00%. Vineland social adaptive score - risk of bias: Adj R2 = 100.00%. The bold values represents the p value < 0.05.
